Hi markokrstic,
If you are using no-source code version, then go to following path and open 980.css file.
Themes\Urban\Content\css\980.css
If you are using source code version, then go to following path and open 980.css file.
Presentation\Nop.Web\Themes\Urban\Content\css\980.css
In 980.css file, look for the following block of code.
.home-page .home-page-product-grid .title,
.home-page .bestsellers .title{
float:left;
width:23.5%;
height: 400px;
margin:0 0 0 1%;
padding: 0;
font-size:72px;
line-height:72px;
word-wrap:break-word;
text-align:left;
background: url("../img/shadow-left.png") no-repeat right center;
}
In this code, set font-size to 38px or any other value you prefer.
"Featured Products" and "Bestsellers" texts will be affected (resized) accordingly. This is the css file of urban theme that you need to make changes on urban theme's home page.
