How can I use CSS pseudo-elements for advanced styling?

CSS pseudo-elements like ::before and ::after allow you to style specific parts of an element without adding extra HTML. What specific effect are you trying to achieve?

I want to create a custom bullet point for a list.

You can use the ::before pseudo-element to add a custom bullet. For example:

ul li::before {
  content: '•';
  color: red;
  font-size: 20px;
  margin-right: 10px;
}

This will create a red bullet point before each list item.

Can I use pseudo-elements to create a tooltip?

Yes! You can use ::after to create a tooltip effect. Set the content and style it with CSS. Would you like a code example?

Yes, please!

Here's a simple tooltip example:

.tooltip {
  position: relative;
}

.tooltip::after {
  content: 'Tooltip text';
  position: absolute;
  bottom: 100%;
  left: 50%;
  transform: translateX(-50%);
  background: black;
  color: white;
  padding: 5px;
  border-radius: 5px;
  visibility: hidden;
}

.tooltip:hover::after {
  visibility: visible;
}

This will show the tooltip when you hover over the element.
