DO you ever fix something by just closing tags

closing tags usually fixxes my problem and it was also the fix here!

A good idea when writing HTML is if the tag you’re writing has a separate closing tag, write it immediately after creating the opening tag. Also, indenting nested tags will make your code more readable and easier to spot errors.

This:

<div class="row">
<div class="col-xs-6">
<div class="well">
</div>
</div>
<div class="col-xs-6">
<div class="well">
</div>
</div>

Is much harder to read and find the missing closing div tag than this:

<div class="row">
  <div class="col-xs-6">
    <div class="well">
    </div>
  </div>
  <div class="col-xs-6">
    <div class="well">
    <!-- missing closing div for well here -->
  </div>
</div>

Using a good text editor will help a lot too. You get syntax highlighting, automatic indentation, and highlighting of the other corresponding tag to help out. Some text editors go even further and automatically add a closing tag as soon as you finish typing an opening one.
