I was on the google news page and I was wondering how do google make his border around each sections, because I can't find in the inspector any element with a border property. I find those borders very thin. Thanks for your help .
if you inspect well, then you will see its a
box-shadow instead of border, Here is what they used in their css, Please check again,
box-shadow: 0 1px 3px 0 rgba(0,0,0,0.16), 0 0 0 1px rgba(0,0,0,0.04); background-color: #fff;
Hint: check for class
