Can You Change the Color of the Last Letter in a String Using CSS?

Can You Change the Color of the Last Letter in a String with CSS?

It has often been asserted that you cannot use CSS alone to change the color of the last letter in a string. However, it turns out that this is not entirely true.

Solution

By leveraging two clever CSS features, we can achieve this unconventional styling:

Reverse Text Flow: CSS provides a way to reverse the direction of text flow, using the unicode-bidi: bidi-override; property. By doing so, the letters appear in reverse order, effectively reversing the text direction.
Pseudo-Element Selector: CSS offers the ::first-letter pseudo-element selector, which targets the first letter of the text. Since the text is reversed, this selector will effectively target the last letter of the actual text.

Example Markup:

To demonstrate the effect, consider the following markup:

<code class="html"><div>gnirtS</div></code>

Copy after login

Example CSS:

<code class="css">div {
  float: left;
  unicode-bidi: bidi-override;
  direction: rtl;
}

div::first-letter {
  color: blue;
}</code>

Copy after login

Explanation:

The

element is first set to float left to prevent it from affecting the layout of surrounding elements. The unicode-bidi and direction properties are applied to reverse the text flow (right-to-left).

Finally, the div::first-letter selector is used to target the first letter of the reversed text, which corresponds to the last letter of the actual string ("g" in this case). It is styled with a blue color.

Conclusion:

Through this innovative combination of CSS features, you can indeed change the color of the last letter in a string using CSS alone, proving that sometimes even perceived limitations can be overcome with clever thinking.
