margin or padding of full-width pages

margin or padding of full-width pages

Hi,
I want to change margin or padding of full-width pages.(including content area and comment area)

<div id=”content” class=”full-width”>

<section id=”main-content” role=”main”>
</section>

</div>

I try to change style.css like this:

#content.full-width
{ width: 100%;padding-left:50px;padding-right:50px;}

The “margin-left” and “padding-left” did work, but “margin-right:50px;” or “padding-right:50px;” didn’t work.

And when I change the margin-left or padding-left, words of right side were cut off.

Thanks in advance!
