Question

As you can see on this screenshot the close button is not styled properly on my website.

I use bootstrap with less and I could not find the button.close class in my less code (I could find this class in this bootstrap page).

I suppose it’s supposed to be in close.less ?

At least when I add it here it works.

Answer 1

button.close is in close.less

https://github.com/twitter/bootstrap/blob/master/less/close.less

make sure you are using

<button type="button" class="close" data-dismiss="alert">×</button>

and not

<button type="button" class="close" data-dismiss="alert">x</button>

for elder version of the twitter bootstrap and iso-8859-1, try with utf-8.

If you still have problems, use jsFiddle to post your code and I will have a look.
