Can you style a <abbr> tag?

Can you style a <abbr> tag using css? In firefox, it is displayed with dots underneath the words like in the picture below:

Is this a browser by browser thing? can you remove the dots or do you just use the title="title here" option? thanks

• Can you style a tag using css?

  Yes, you can.

• In firefox, it is displayed with dots underneath the words

  Yes. Firefox default style is

  abbr[title], acronym[title] {
      border-bottom: 1px dotted;
  }
  

• Is this a browser by browser thing?

  Yes, this behaviour is determined by the default stylesheet of each browser. Then, different browsers may display it different by default.

• Can you remove the dots?

  Yes, just override the default syle:

  abbr[title], acronym[title] {
      border-bottom: none;
  }
