This CSS is a selector that allows you to choose a CSS element and insert content before every element with a specific class applied to it. Let’s say you had a website where you wanted specific text before every H2 tag. You would us this setup:
Like the :before selector, you can use :after to insert content globally on specific elements. A practical use would be adding “read more” after every excerpt on a blog. Here’s how you would do that.
h2:before {
content: "Read: ";
<span class="Apple-converted-space"> color: #F00;</span>
}
p:after{
content: " -Read more… ";
color:#f00;
}
