Is using <div> spacers a bad practice? [closed]

Question

Is it a bad practice to use <div> tags to express gaps between elements? If yes - why is it so?

Here's an example:

<div class="panel">     <!-- Content --> </div>  <div class="spacer"></div>  <div class="panel">     <!-- Content --> </div> 

The CSS:

div.spacer {     font-size: 0;      height: 10px;     line-height: 0; } 

Answer 1

It's bad if you could add a margin to content instead. Otherwise, it's the best HTML element for spacers.
