How can I create a Chevron Arrow using CSS Techniques?

Achieving a Chevron Arrow with CSS Techniques

Creating a chevron arrow, characterized by two diagonal lines intersecting at a point, using CSS can be accomplished with various approaches.

One method utilizes pseudo-elements like before or after, which are applied with CSS properties. By adding both before and after elements, rotating them, and positioning them strategically, the arrow shape is formed. Alternatively, you can add two borders to the before element and rotate it using transform: rotate.

Another approach involves using an actual HTML element instead of pseudo-elements. This can be done by incorporating arrows as bullets in a list. By using em units for the arrow dimensions, you can ensure they scale appropriately with the font size of the list.

The following CSS code demonstrates the latter approach:

<code class="css">ul {
  list-style: none;
}

ul.big {
  list-style: none;
  font-size: 300%
}

li::before {
  position: relative;
  content: "";
  display: inline-block;
  width: 0.4em;
  height: 0.4em;
  border-right: 0.2em solid black;
  border-top: 0.2em solid black;
  transform: rotate(45deg);
  margin-right: 0.5em;
}

li:hover {
  color: red; /* For the text */
}

li:hover::before {
  border-color: red; /* For the arrow (which is a border) */
}</code>

HTML code showing the usage:

<code class="html"><ul>
  <li>Item1</li>
  <li>Item2</li>
  <li>Item3</li>
  <li>Item4</li>
</ul>

<ul class="big">
  <li>Item1</li>
  <li>Item2</li>
  <li>Item3</li>
  <li>Item4</li>
</ul></code>
