Implementing a Keyboard Shift Button Using HTML/CSS

In web design and development, HTML and CSS are used to fulfill specialized button needs, like simulating a keyboard shift button. This button mimics the keyboard’s shift key for specific functions such as triggering caps lock.

By replicating the keyboard shift button, we create a button that looks and behaves like the actual keyboard shift key.

Here is the specific code:

HTML

<button class="button">
  shift
</button>

CSS

.button {
  display: flex;
  flex-direction: column;
  align-items: flex-start;
  justify-content: flex-end;
