CSS Selector Classes on an ID
Want to add a combination of ID and class to a selector? Here’s a nice little piece of CSS. Let’s say you have code like this:
If you want to write a selector based on that element having both that ID and class name in combination (for an even tighter degree of specificity), you can write that selector like so:
div#foo.bar
That CSS selector will match your element. Again, the format is element#id.class.
