There is no problem to add pure css
.myclass1{
padding-left: 10px;
}
via Google Chrome Styles tab (F12 -> Styles tab -> click on + sign to add styles).
However, I'm having difficuitlies to add a media query
@media (min-width: 800px){
.myclass1{
padding-left: 10px;
}
}
Is there any way to do that?
Just added: I would like to add similar css to what is on the image below.
Instead of going into styles try the main html in the left panel, right click the head tab and click on edit as HTML then just add your code.
