Customizing Styles

Highlight tokens

All highlight tokens of matching searched text will be wrapped in a <mark class="find-in-nw-token">searched text</mark>.

They will also contain a data-find-in-nw-position="4" data attribute, the number correlates to a zero-based index of all matches.

As you navigate from one match to the next, the currently selected match will have a class of .find-in-nw-current-token.

You can customize this by targeting the following

mark.find-in-nw-token {
    background-color: #00F;
}

mark.find-in-nw-current-token {
    background-color: #38D878;
}

Search Box

Each element of the search box is styled by targeting a class. They also all have a matching ID that you can target to override them.

/* The container for the input/count/close */
#find-in-nw-search-box {}

/* The input field you type in */
#find-in-nw-input {}

/* The current selected match number. Ex: The number 1 in "1/5" */
#find-in-nw-current {}

/* The separator between the current and count. Ex: The slash (/) in "1/5" */
#find-in-nw-of {}

/* The count of matching highlighted items. Ex: The number 5 in "1/5" */
#find-in-nw-count {}

/* The previous and next buttons, ∧ and ∨ */
#find-in-nw-previous {}
#find-in-nw-next {}

/* The × close button */
#find-in-nw-close {}
