Exploring the world of CSS selectors can be quite fascinating.
These selectors allow you to target different elements within your HTML structure.
An Example of Selectors in Action
.button span {
...
}
A common usage of selectors is illustrated through "descendants".
The code .button span
essentially means HTML with a class of "button" and containing a nested span
element.
This would result in:
.button span {
color: red
}
<button class="button">
Button Text
</button>
<button class="button">
Some text
<br />
<span>I'm Red</span>
</button>
<button>
Some text
<span>I'm not Red</span>
</button>
Another Example
The selector .button span:after
, combines descendant selection with the use of "&".
It includes the pseudo-element :after
at the end of the span
.
Pseudo-elements are denoted by a ":" before them, such as :hover
for mouse events or :before
/:after
for other purposes.
.button span:hover {
color: red;
}
<button class="button">
Button Text
</button>
<button class="button">
<span>I'm Red when you hover on me</span>
<br/>
But I will never be red when you hover
</button>
<button>
<span>I'm not Red when you hover</span>
</button>
<div class="button">
<span>I will be red when you hover on me</span>
</div>
