It is the most well-known and widely used CSS framework, providing a collection of ready-made HTML, CSS, and JavaScript templates for common interface components. + +While modern trends often favor utility-first systems like Tailwind CSS, Bootstrap remains an excellent choice for rapid prototyping, developing standard enterprise applications, and ensuring a consistent, accessible baseline design with minimal effort. + + +
+ +## 1. Core Concept: Component-Based Design + +Bootstrap operates on a **component-based** philosophy. Instead of applying individual styling utilities, you apply a single semantic class that bundles all the necessary styles, states, and responsive behavior for a common UI element. + +### Component Example + +To create a primary-style button, you simply use the predefined classes: + +```html title="index.html" + + + +``` + +### Key Advantages + + * **Rapid Prototyping:** Components look good out of the box, requiring minimal custom CSS. + * **Consistency:** Provides a standard, cohesive look across the entire application. + * **Ease of Use:** Low barrier to entry; developers only need to learn the class names, not the underlying CSS properties. + +## 2. The Responsive Grid System + +Bootstrap's most enduring and crucial feature is its Flexbox-based 12-column responsive grid system. It allows developers to define complex layouts that adapt seamlessly across various screen sizes using predefined classes. + +### Grid Structure + +The grid is built on three core concepts: + +1. **Containers:** `.container` (fixed width based on breakpoint) or `.container-fluid` (full width). +2. **Rows:** `.row` creates a horizontal group for columns, ensuring correct negative margin and Flexbox behavior. +3. **Columns:** `.col-*` classes define the number of columns (out of 12) a section should span. + +### Column Breakpoints + +Bootstrap uses five default breakpoints to control column stacking and size: + +| Prefix | Breakpoint | Device Type | Purpose | +| :--- | :--- | :--- | :--- | +| `col-` | $\lt 576px$ | Extra Small (Mobile) | Stacks vertically by default. | +| `col-sm-` | $\ge 576px$ | Small (Landscape Mobile) | Defines behavior for small screens and up. | +| `col-md-` | $\ge 768px$ | Medium (Tablet) | Defines behavior for tablets and up. | +| `col-lg-` | $\ge 992px$ | Large (Desktop) | Defines behavior for desktops and up. | +| `col-xl-` | $\ge 1200px$ | Extra Large | Defines behavior for large desktops. | + + +
+ +### Responsive Grid Example + +This layout stacks on mobile, shows two equal columns on tablets, and three equal columns on desktops. + +```html title="index.html" +

+``` + +## 4. Customization and Styling + +Modern Bootstrap is highly customizable, moving away from the rigid themes of its early versions. + +### A. Sass Variables + +Bootstrap's source code is built with **Sass (SCSS)**. The most scalable way to customize Bootstrap is to override its default variables *before* the Sass files are compiled. This allows you to change global defaults like primary colors, font stacks, and spacing increments. + +```scss title="custom/_variables.scss" +// 1. Override Primary Color +$primary: #007bff; // Default blue +$primary: #4CAF50; // Custom green + +// 2. Override Border Radius +$border-radius: 0.5rem; +$border-radius-lg: 0.75rem; + +// Must import Bootstrap after defining variables +@import "bootstrap/scss/bootstrap"; +``` + + +
+ +### B. Utility API + +Since Bootstrap 4, the framework has incorporated an increasing number of reusable utility classes (similar to Tailwind, but less comprehensive). These are primarily used for small adjustments like margin, padding, and display properties. + +| Utility Class | Description | +| :--- | :--- | +| `m-3` | Sets `margin` on all sides to 1rem. | +| `pt-4` | Sets `padding-top` to 1.5rem. | +| `d-flex` | Sets `display: flex;`. | +| `text-center` | Sets `text-align: center;`. | + +These utilities are essential for fine-tuning the spacing and alignment of pre-built components without needing to write custom CSS. + +## Try It Out + +Now that you've seen the basics of Bootstrap's component-based framework, responsive grid system, and customization options, it's time to try it yourself! + + \ No newline at end of file diff --git a/docs/css/css-frameworks/bulma.mdx b/docs/css/css-frameworks/bulma.mdx index e345ed2..3255de2 100644 --- a/docs/css/css-frameworks/bulma.mdx +++ b/docs/css/css-frameworks/bulma.mdx @@ -1 +1,168 @@ - \ No newline at end of file +--- +title: "Bulma (Flexbox-First Framework)" +description: "Explore Bulma, a modern, lightweight, and responsive CSS framework based entirely on Flexbox, offering intuitive components and an easy-to-read utility class structure." +keywords: [Bulma CSS, Flexbox framework, CSS components, responsive design, modular CSS, lightweight framework] +tags: [Bulma CSS, Flexbox framework, CSS components, responsive design, modular CSS, lightweight framework] +sidebar_label: Bulma +--- + +Bulma is a modern, open-source CSS framework that distinguishes itself by being built entirely on **Flexbox**. Unlike older frameworks, Bulma is purely CSS, it provides no built-in JavaScript components, making it lightweight and easy to integrate with any JavaScript framework (React, Vue, Angular, etc.). + +Bulma is known for its highly readable class names and its strong focus on a clean, modular component architecture, offering a refreshing alternative to larger, more traditional frameworks. + + +
+ +## 1. Core Philosophy: Pure CSS and Modularity + +Bulma's core design principles prioritize simplicity and separation of concerns: + +### A. Pure CSS + +Bulma consists only of CSS files. All interactive components (like dropdowns, modals, and tabs) require developers to supply their own JavaScript implementation to manage the necessary `is-active` or `is-hidden` state classes. This gives developers complete control over the front-end logic. + +### B. Modularity + +Bulma's source code is modular, broken down into 39 individual Sass files. This allows developers to easily import only the specific components they need (e.g., just the grid and buttons) to minimize the final stylesheet size. + +### C. Readable Class Names + +Bulma uses highly descriptive, hyphenated class names that are easy to remember and understand, such as `is-primary`, `is-fullwidth`, or `has-text-centered`. + +## 2. The Responsive Flexbox Grid + +Since Bulma is Flexbox-based from the ground up, its grid system is highly flexible and intuitive, relying on the `columns` and `column` classes. + +### A. Structure + +1. **Container:** `.container` (fixed width, centered) or `.is-fluid` (full width). +2. **Columns Wrapper:** `.columns` initializes the Flexbox container, providing necessary negative margins and spacing. +3. **Columns:** `.column` acts as the flexible item inside the wrapper. + +### B. Size and Breakpoints + +Columns are defined by using the fraction of the 12-column grid system (e.g., `is-half` for 6/12, `is-one-third` for 4/12). + +Bulma uses four main breakpoints: + +| Prefix | Breakpoint (Min-Width) | Device Type | Purpose | +| :--- | :--- | :--- | :--- | +| `is-mobile` | Default | Mobile (Default Stack) | Mobile-only classes. | +| `is-tablet` | $\ge 769px$ | Tablet | Defines behavior for tablets and up. | +| `is-desktop` | $\ge 1024px$ | Desktop | Defines behavior for desktops and up. | +| `is-widescreen` | $\ge 1216px$ | Large Desktop | Defines behavior for larger screens. | + +### Responsive Grid Example + +This layout uses three equal columns on tablet size and larger, and stacks vertically on mobile. + +```html title="index.html" +

Unlike traditional component-based frameworks (like Bootstrap, which provides pre-styled buttons and cards), Tailwind provides low-level, atomic utility classes that you apply directly in your HTML markup to build highly customized designs quickly. + +It is often described as "a highly customizable, low-level CSS framework that gives you all of the building blocks you need to build bespoke designs without ever leaving your HTML." + + +
+ +## 1. Understanding the Utility-First Philosophy + +In traditional CSS, you write semantic class names (e.g., `.card`, `.button-primary`) and then define all styles for that class in a separate CSS file. + +In the utility-first approach, you apply granular, single-purpose classes directly to your elements. + +### Traditional CSS vs. Utility-First + +| Concept | Traditional CSS (e.g., Bootstrap) | Utility-First (Tailwind) | +| :--- | :--- | :--- | +| **Styling Location** | Separate `.css` or `.scss` file. | Directly in the HTML `class` attribute. | +| **Class Name** | Semantic, high-level (e.g., `.btn-success`). | Atomic, single-property (e.g., `bg-green-500`, `py-2`). | +| **Scalability Issue** | Class name conflicts and cascade side effects. | Low specificity and localized styles eliminate cascade issues. | +| **Development Speed**| Context switching (HTML $\to$ CSS $\to$ HTML). | Extremely fast—no context switching required. | + +### The Tailwind Example + +To create a blue button with rounded corners and bold text: + +```html title="index.html" + + +``` + + +
+ +:::note Fundamental Utility Categories + +Tailwind organizes its classes based on standard CSS properties. Every class is an abbreviation of a CSS property and value. + +| Category | Example Class | CSS Property / Value | Purpose | +| :--- | :--- | :--- | :--- | +| **Layout** | `flex`, `grid`, `col-span-4` | `display: flex;`, `grid-template-columns`, etc. | Controlling containers and grids. | +| **Spacing** | `p-4`, `mx-auto`, `space-y-2` | `padding`, `margin`, `gap` | Controlling element spacing. | +| **Typography** | `text-xl`, `font-bold`, `leading-snug` | `font-size`, `font-weight`, `line-height` | Styling text. | +| **Backgrounds** | `bg-red-500`, `bg-opacity-75` | `background-color`, `opacity` | Controlling backgrounds. | +| **Borders** | `border-2`, `rounded-lg`, `shadow-xl` | `border-width`, `border-radius`, `box-shadow` | Styling outlines and effects. | +| **Interactivity** | `cursor-pointer`, `hover:bg-blue-700` | `cursor`, pseudo-classes | Handling user input and states. | + +::: + +## 2. Core Advantages of Tailwind CSS + +Tailwind solves common pain points in large-scale CSS development, making it highly scalable and maintainable. + +### A. Eliminates the Cascade Problem + +The biggest challenge in large CSS projects is the global nature of the cascade. Tailwind minimizes this problem because: + + * **Low Specificity:** All utility classes are single classes, meaning their specificity is low (`0,1,0,0`). + * **Localized Styles:** Styles are applied directly to the element, making them highly localized and preventing them from interfering with other components. + +### B. Speeds Up Development (No Context Switching) + +By using utilities, developers rarely have to leave the HTML file to write custom CSS. This dramatically speeds up the development feedback loop and component creation process. + +### C. Forced Constraints and Consistency + +Tailwind is built on a predefined design system (or "design tokens"). This means you are limited to a specific scale for spacing (`p-1` through `p-96`), color palettes, and font sizes. This forced constraint ensures visual consistency across the entire application. + +### D. Built-in Responsiveness + +Tailwind's responsive design is baked directly into the utility classes using prefixes, which map directly to common CSS media queries. + +| Prefix | Breakpoint | Target Size | Example | +| :--- | :--- | :--- | :--- | +| (None) | Default | Mobile-first | `w-full` | +| `sm:` | $640px$ | Small screens/Tablets | `sm:flex` | +| `lg:` | $1024px$ | Desktops | `lg:w-1/2` | + +```html title="index.html" + +
...
+``` + + +
+ +:::note Key Advantages + + * **Speed:** Develop faster as you never leave your HTML file to write CSS. + * **No Naming Decisions:** Eliminate "CSS naming wars" (BEM, SMACSS) as the class names are predefined and descriptive (e.g., `p-4` means padding of 1rem). + * **Scalability:** Since styles are localized to the element, you virtually eliminate side effects and cascade conflicts when scaling your application. + * **Predictability:** The styles on an element are immediately obvious just by reading the class list. +::: + +## 3. Configuration and Customization + +Tailwind is not a closed system; it is designed to be deeply customized to fit any design system. + +### The `tailwind.config.js` File + +All colors, spacing values, breakpoints, and font families are configured in this central JavaScript file. + +```js title="tailwind.config.js" +module.exports = { + theme: { + extend: { + colors: { + // Add a custom brand color + 'primary-brand': '#5c6ac4', + }, + spacing: { + // Add a custom spacing unit + '128': '32rem', + } + } + }, + plugins: [], +} +``` + +Once configured, the new color can be used instantly: `bg-primary-brand`, `text-primary-brand`. + +## 4. Performance and Production Build + +While using many classes in HTML might seem inefficient, Tailwind's production process makes the final CSS bundle highly performant. + +### PurgeCSS (PostCSS) + +In development, Tailwind generates a massive CSS file containing thousands of potential utility classes. However, in the production build step, a process called **Purging** is executed: + +1. A tool (like PurgeCSS) scans all your HTML and JavaScript files. +2. It identifies **only** the utility classes you actually used (e.g., `bg-blue-500`, `py-2`, `md:flex`). +3. It removes all unused CSS, resulting in a tiny, optimized production stylesheet, often under $10\text{KB}$ compressed. + +### The Final CSS + +The final, shipped CSS file only contains the styles that are absolutely necessary for your application, ensuring lightning-fast load times. + +```css title="styles.css" +/* Final Production CSS after Purging */ + +.bg-blue-500 { background-color: #3b82f6; } +.hover\:bg-blue-700:hover { background-color: #1d4ed8; } +.py-2 { padding-top: 0.5rem; padding-bottom: 0.5rem; } +.md\:flex { @media (min-width: 768px) { display: flex; } } +/* ... and so on for only the used classes */ +``` + + +
+ +## 5. Integrating Tailwind with Components + +While Tailwind encourages applying styles directly in HTML, maintaining long lists of classes can become unwieldy. There are several ways to manage complexity: + +### A. Framework Components (React/Vue/Angular) + +The best way to use Tailwind is within component-based frameworks. The component handles the encapsulation of the lengthy class string. + +```jsx title="MyButton.jsx" +// React Example (Simplified) +const MyButton = ({ children, primary }) => { + const baseClasses = "font-bold py-2 px-4 rounded shadow-md transition duration-300"; + const colorClasses = primary + ? "bg-indigo-600 hover:bg-indigo-700 text-white" + : "bg-gray-200 hover:bg-gray-300 text-gray-800"; + + return ( + + ); +}; +``` + +### B. `@apply` Directive + +For situations where you need to extract and reuse a set of utilities without a JS framework, you can use the PostCSS `@apply` directive within a custom CSS file. + +```css title="custom-components.css" +.btn-cta { + /* Groups several utility classes into one semantic class */ + @apply bg-blue-600 text-white font-semibold py-3 px-8 rounded-lg shadow-xl hover:bg-blue-700 transition duration-300; +} +``` + +You can then use the custom class in your HTML: + +```html title="index.html" + +``` + + + + + + +
+ +## 6. Responsive Design + +Tailwind CSS is mobile-first by default, making responsive design simple and intuitive. You apply specific breakpoints using prefixes: + +| Prefix | Breakpoint | Media Query (Min-Width) | Applied To | +| :--- | :--- | :--- | :--- | +| (None) | Default (Mobile) | N/A | All devices | +| `sm:` | Small | `640px` | Small screens and up | +| `md:` | Medium | `768px` | Tablets and up | +| `lg:` | Large | `1024px` | Desktops and up | + +### Responsive Example + +In the example below, the layout stacks vertically on mobile (`flex-col`) but becomes horizontal on medium screens and larger (`md:flex-row`). + +```html title="index.html" +
+ + +
+ +
+ + +

+ Fluid Content +

+
+``` + +## 7. State Variants + +Tailwind provides pseudo-classes as prefixes, allowing you to define styles that only apply in specific interactive states. + +| State Prefix | CSS Pseudo-Class | Purpose | +| :--- | :--- | :--- | +| `hover:` | `:hover` | Apply styles when the mouse hovers over the element. | +| `focus:` | `:focus` | Apply styles when the element is active or focused (keyboard navigation). | +| `active:` | `:active` | Apply styles when the element is being clicked/pressed. | +| `group-hover:` | (Custom) | Allows styling a *child* element when the *parent* has a `hover` state. | + +### State Example + +```html title="index.html" + +

+ This text changes color on hover. +

+ +``` + + +
+ +## 8. JIT Compilation (The Modern Engine) + +Modern Tailwind relies on the **Just-in-Time (JIT)** engine. This is crucial for performance and scalability. + +1. **On-Demand CSS:** Tailwind only generates the CSS required by the utility classes found in your HTML and JavaScript files. +2. **Tiny CSS Bundles:** This process ensures your final production CSS file is minimal, containing only used styles, making load times extremely fast. +3. **Automatic Purging:** Since unused styles are never generated, you don't need a separate purging tool. + +:::tip Key Takeaway +Tailwind CSS forces developers to think in terms of small, composable building blocks, mirroring modern component-based JavaScript architecture. This dramatically improves the maintainability and scalability of large CSS codebases by simplifying the cascade and eliminating global side effects. +::: + +## try it out + +Now that you've seen the basics of Tailwind CSS's utility-first framework, responsive design, and customization options, it's time to try it yourself! + + + +## Resources for Further Learning + +* [Official Tailwind CSS Documentation](https://tailwindcss.com/docs) +* [Tailwind CSS GitHub Repository](https://github.com/tailwindlabs/tailwindcss) \ No newline at end of file diff --git a/static/img/html-css-js.jpg b/static/img/html-css-js.jpg new file mode 100644 index 0000000..dfb380f Binary files /dev/null and b/static/img/html-css-js.jpg differ
