How to find whitespaces and remove them PhpStorm?

Question

Based on this question I have a new question. I'm using PhpStorm to create my php files and my markup looks like this:

<div>
     <div>
     </div>
</div>

The different spacing is made automatically when pressing enter. But recently I had a new problem (see link above). I had whitespaces which I couldn't delete the only way that worked was not using a new line with a tab like:

<div><div>
</div>
</div>

I tried to remove it by selecting the text between the divs like:

and then pressing enter. The result after: (note: I didn't add a tab its added automatically):

But why is this code containing whitespaces? I never had problems with it before.

(please view the linked question to see the problem it creates, didn't add it here to make the question more readable)

Answer 1

In HTML, all whitespace (including tabs, new lines, and regular spaces) is treated the same. If you need to eliminate all spaces, deleted the new line inside the inner <div> .
