auto space between horizontal divs in CSS

Question

I\'ve searched a lot but I was not lucky to find a solution to what I am after!

Here is the issue: I\'ve created a master div (width 100%) and within it there are severa

Answer 1

Here is JSFiddle

Assume that you have 100% and you have 4 pieces. 4 pieces means you have 3 margin-left block so, when you make your div 22*4=88 then 100-88=12 then 12/3=4 then your margin-left must be:4

div.box_frame{
    float: left;
    background-color: #eee; /* standard background color */
    border: 1px solid #898989; 
    border-radius: 11px;
    padding: 2px;
    margin-left:4%;
    text-align: center;
    /* change border to be inside the box */
    box-sizing:border-box;
    -moz-box-sizing:border-box;
    -webkit-box-sizing:border-box;
}
div.box_frame:first-child{
    margin-left: 0;
}
div.box_frame#_15{ /* width 15% */
    width: 22%;
}

So if you use less variables then you can use this solution without depending on number of div blocks
