Applying CSS rules only if an element is specified for 2 classes

Question

CSS selector that applies to elements with two classes

Is there a way to apply CSS style to an element only if 2 classes are applied to it?

For example, apply my custom styles to this:

<div class="one two">Text</div> 

But not to these:

 <div class="one">Text</div> <div class="two">Text</div> 

Answer 1

Of course:

 .one.two { border: 1px red solid } 

Answer 2

Try using css .one.two in the selector
