Hello,

Sorry for the late reply.
1-How many colulmns do you have in your mega-menu? To change the width please add this code into your custom css box:

nav .codeless_custom_menu_mega_menu.codeless_mega3 li {
    width: 185px !important;
}

If this won’t do, send us your site’s url so i can give you a more specific code.
2- Do you mean the single article or the article in a blog page? Please send us a link where you want this edit.

3-change the distance of sidebar from content, by setting padding to the span9 and span3. Add the custom css into your custom css box.

Best regards!

Hello,

1-I see from the inspect element that you have indeed added the css code for mega menu. I made another test by increasing the value and it does change mega menu column width (screenshot). What is not working for you?

2-Pagination is only for blog pages not blog elements used in other pages. So if you want ot use pagination, you have to use it in blog page, not in any of Visual Composer blog elements.
To remove the “0 comments” from single posts, add this code into your custom css box:

.single #comments {
    display: none;
}

Let us know.

Best regards!
