How do you adjust the collar here?

Hi,

You need to use the tagDiv Composer, edit the homepage, click on the elements you want to edit -> http://prntscr.com/ppho9m -> http://prntscr.com/pphomj -> http://prntscr.com/pphot4

Thank you!

Hello,

Unfortunately on category page you can change the background color only with custom css -> http://prntscr.com/pq1kyz, if there is still a problem, please provide me a link where I can check your categories.
.td-subcategory-header .td-category a{
background-color: #f22;
color: #fff;
}
.td_category_template_1 .td-category-header .entry-title span {
background-color: #2f2;
}
The code need to be set in Theme panel> Custom code> Custom css

Thank you!
