Starting from Ultimate Web Builder 3.4 - all versions! - we have made it a lot easier to format your webpages further than the Page Format you choose, using Divs.  No coding necessary.

You can (A) Set a Div Format for a one paragraph section, overriding the Paragraph Formar, or, (B) Wrap a Div around a Paragraph Format, to have several paragraphs in the Div.

Here's how:

1) On the Content Editor Box, click or highlight on the content you want to stylize. *For Type (B): Highlight all the paragraphs you want to wrap the Div around.

2)

Type (A): From the format menu, you can choose the format type.  Default setting is "Paragraph".

Choose "DIV" from the menu here, click to highlight.  When it's selected, there will be a checkmark next to it, next time you open this menu and are on this content section that you applied this format to.

Type (B): When you choose "Div", in the menu directly next to it, "Div Wrap" will be automatically highlighted and checkmarked.  

3) On this menu, you can stylize the div - set the alignment and choose the width by clicking on the option(s) you would like. The menu item(s) will be highlighted and checkmarked as well:

Scroll down this menu for even more options, such as setting a background color for the div, or margins or font colors:

Note: You can set the Background Colors on the Configure Site > Styles Manager, Extras section.  

Changing them there updates all instances! Easy updating!

 
Back to the CMS Page Editor Box....you can also easily add padding:

Add a border with the style you want:

You can also choose a border width. And even create rounded edges, on all four edges, or the top two or bottom two:

Notice on the bottom of this menu there are Expand Div options to make your div responsive. You can expand divs that are not 100% width to go to 100% when the window screen reaches a certain width.

And, of course, you are free to edit your coding directly in the Page Editor Box - just click on the <> code button to view/edit your code.
