How Can You Style Half a Character in CSS and JavaScript?

The Enigma of Stylizing Half a Character: A CSS and JavaScript Odyssey

In the realm of web aesthetics, the pursuit of perfection often leads us to seek unconventional solutions. One such enigma is the elusive challenge of styling a mere half of a character. Whether it be for artistic expression or functional purposes, the question of how to divide a single character's visual real estate has intrigued developers for years.

The Quest for Partial Character Styling

Through countless searches and experiments, countless developers have attempted to find an elegant CSS or JavaScript solution that can selectively style half of a character, while preserving its accessibility for screen readers and maintaining its semantic meaning.

The CSS Solution for a Single Character

For a single character, there exists a pure CSS solution that relies on the clever use of pseudo-elements:

<code class="css">.halfStyle {
  position: relative;
  display: inline-block;
  font-size: 80px;
  color: black;
  overflow: hidden;
  white-space: pre;
}

.halfStyle:before {
  display: block;
  z-index: 1;
  position: absolute;
  top: 0;
  left: 0;
  width: 50%;
  content: attr(data-content);
  overflow: hidden;
  color: #f00;
}</code>

By utilizing the ::before pseudo-element, we create a transparent overlay that covers the left half of the character, revealing only the desired half in color.

The JavaScript Solution for Dynamic Text

For dynamic text or multiple characters, we employ JavaScript automation:

<code class="javascript">// Iterate over all occurences of 'textToHalfStyle' class
$('.textToHalfStyle').each(function(idx, el) {
  var text = $(el).text(),
      chars = text.split('');

  // Set screen-reader text
  $(el).html('<span style="position: absolute !important;clip: rect(1px 1px 1px 1px);clip: rect(1px, 1px, 1px, 1px);">' + text + '</span>');

  var output = '';

  // Loop through all characters
  for (i = 0; i < chars.length; i++) {
    // Create a styled span for each character
    output += '<span aria-hidden="true" class="halfStyle" data-content="' + chars[i] + '">' + chars[i] + '</span>';
  }

  // Write to DOM
  $(el).append(output);
});</code>

JavaScript automates the creation of styled spans for each character, preserving screen-reader accessibility while providing the desired half-character effect.

Conclusion

While the quest for character division may not be an everyday design requirement, it showcases the endless possibilities of CSS and JavaScript to manipulate visual elements in ways that were once thought impossible. Embarking on such quests not only pushes the boundaries of web development but also inspires innovation and exploration in the realm of digital creativity.
