How to make a button position independent using OOCSS? - oocss

Question

I have a button with the following style:
.btn
{
width: 100px;
height: 40px;
float: right;
display: inline-block;
background-color: #555555;
border:1px solid #ffffff;
font-family:OpenSansRegular;
font-size:15px;
color: #ffffff;
}
As I reckon, using OOCSS principles, we should separate visual from structure.
Something like this (I would assume - correct me if I'm wrong):
.btn
{
width: 100px;
height: 40px;
float: right;
display: inline-block;
}
.skin
{
background-color: #555555;
border:1px solid #ffffff;
font-family:OpenSansRegular;
font-size:15px;
color: #ffffff;
}
But what if I want to use the exact same configurations for another button, except for the floating position which I would like to remove, how should I do it? Isn't OOCSS being restrictive by coupling the positioning in the structure?

Answer 1

This likely depends on what exactly the structure you actually have is, but I would likely do something like the following which still follows OOCSS principles:
.btn { /* Default button structure properties */
width: 100px;
height: 40px;
display: inline-block;
}
.float-right { /* More specific button structure properties */
float: right;
}
.skin { /* Default button skin properties */
background-color: #555555;
border: 1px solid #ffffff;
font-family: OpenSansRegular;
font-size: 15px;
color: #ffffff;
}
The actual class names could be different, but given you only have one more specific property, I think the specific name makes sense in this case.
