PubStore Pro whole page background color or background image on other pages?

Hi, I’m using PubStore Pro theme. I want to create sections on other pages like the ones on default page. For example, I copied code from default section 1 to created page: (added section tag with ID and class)

<section style=”background-color:gray;” id=”welcomesection” class=”welcomewrap”>
[column_content type=”one_half”]
Content
[space height=”25px”]
Content
[/column_content]
[column_content type=”one_half_last”]

[/column_content]
</section>

It displays ok, but background color or image doesn’t display on whole page width, just the center part. Template for page is – Full Width. I have tried to set section width to 100%…
