Animate CSS Auto Height Without Javascript

Web developers rejoice! There's an easy way to animate the height of an HTML element even if the height is dynamic, determined by its content, with only CSS. This is typically used for navigation menus and the like, and now it's much easier to code and maintain.

The strategy is to actually animate the grid-template-rows not the height. For example, take the following HTML markup:

<div class="menu">
  <div class="inner-wrapper">
    <p>Here is some content.</p>
    <p>Here is some content.</p>
    <p>Here is some content.</p>
  </div>
</div>

The CSS for this markup would be:

.menu {
  display: grid;
  grid-template-rows: 0fr;
  transition: grid-template-rows 100ms;
}

.menu.active {
  grid-template-rows: 1fr;
}

.menu .inner-wrapper {
  overflow: hidden;
}

Initially the outer div will be hidden since it has no overflow and the grid template rows are zero. When you add active to the outer div element's class list, the browser will animate the transition from zero row height to 1fr, which essentially means the height it needs for its content to render.

Here's an interesting #CSS method for styling an adjacent element based on whether an <input> is empty or not.

input[type="search"]:placeholder-shown + i {
    /* input is empty */
    display: none;
}

input[type="search"]:not(:placeholder-shown) + i {
    /* input is not empty */
    display: inline-block;
}

In this case I'm hiding and showing a clickable icon that clears the search text if there is any. No JavaScript needed other than the click event 😃.
