Question

Would it be possible to create a css class/id that would add a value(say, padding for example) to another class’s same attrib value?

Let me try to put it down more clearly.

.someClass{
padding: 20px;
}

.thickenMe{
padding: 5px;
}

And when i apply these classes as follows,

<div class='someClass thickenMe'>
<!--planning to beef up this div-->
</div>

This div’s net padding should become 25px.

Would it be possible using css only? Its just a thought!

No. You need to use client-side scripting (i.e. JavaScript) if you want to change attributes dynamically. Or, if you just want to define styles by compiling from some dynamic sources, try LESS or SASS.
