Why Doesn\'t `height: 100%;` Work on a Label Element?

Setting Height: 100% on Label Doesn't Work

In an attempt to align the height of a label element with its parent, height: 100%; was implemented. However, the intended effect did not materialize, leaving the label with an arbitrary height.

Understanding the Issue

When setting height: 100%;, it's important to consider the reference point. In this case, the parent element's height must be explicitly defined to establish a sizing context. Without this context, the browser has no basis for calculating 100% of the height.

How to Resolve

To address this issue, ensure that the label's parent element has a height specified. This can be achieved via CSS or by setting the height attribute in the HTML markup.

Example Code

<code class="css">.parent-element {
  height: 200px;
}

.field label {
  height: 100%;
}</code>

By setting the height of the parent element to 200px, the label element will now correctly occupy 100% of its available vertical space.
