I have the following html. Can I target the label based on its for attribute (so only target this label)?

<label for="something">Text</label>

Solution 1:

You can target the attribute by :

label[for="something"] {
   /* woohoo! */
}

For stands for the attribute name
and ="value" stands for its value.
