Can CSS Half-Style a Character?

Can You Half-Style a Character with CSS?

While seeking a method to style only a portion of a character, such as making half of a letter transparent, you have faced difficulties. You've researched methods for half-character styling, using CSS or JavaScript to achieve this effect, and applying CSS to 50% of a character, but to no avail. You prefer to avoid using images as the text will be dynamically generated.

The CSS Solution

Both CSS and JavaScript solutions exist to achieve your desired effect. Here's how you can approach this using CSS:

Single Character

For a single character, using pure CSS is sufficient. Apply a .halfStyle class to the element containing the character and create a data-content attribute on the same element.

CSS:

.halfStyle {
  position: relative;
  display: inline-block;
  font-size: 80px;
  color: black;
  overflow: hidden;
  white-space: pre; /* to preserve the spaces from collapsing */
}

.halfStyle:before {
  display: block;
  z-index: 1;
  position: absolute;
  top: 0;
  left: 0;
  width: 50%;
  content: attr(data-content); /* dynamic content for the pseudo element */
  overflow: hidden;
  color: #f00;
}

HTML:

<span class="halfStyle" data-content="X">X</span>

Multiple Characters

To apply this style to multiple characters, a JavaScript solution is recommended.

JavaScript:

// jQuery for automated mode
$(function($) {
    var text, chars, $el, i, output;

    // Iterate over all class occurences
    $('.textToHalfStyle').each(function(idx, el) {
    $el = $(el);
    text = $el.text();
    chars = text.split('');

    // Set the screen-reader text
    $el.html('<span>

HTML:

<span class="textToHalfStyle">Half-style, please.</span>

This solution preserves text accessibility for screen readers and is easily automatable across multiple characters.
