CSS Tricks: The Skinny on CSS Attribute Selectors

From the website:

The Skinny on CSS Attribute Selectors | CSS-Tricks

CSS has the ability to target HTML elements based on any one of their attributes. You probably already know about classes and IDs. This single element has three attributes: ID, class, and rel. To select the element in CSS, you could use and ID selector (#first-title) or a class selector (.magical). But did you know you can select it based on that rel attribute as well? That is what is known as an attribute selector:

h2[rel=friend] {
/* woohoo! */
}

There is a lot more to attribute selectors though, so let’s look closer at all the different options and try to cover some “real world” scenarios on when they might be useful.
