Add inner-marging to a 4 columns CSS

I am not a CSS expert (mainly because I haven’t had the need to use much HTML/CSS stuff lately), so I came up with the following style/divs to create a 4 column layout:

    <style type="text/css">
        <!--
        .columns:after {
            content: ".";
            display: block;
            height: 0;
            clear: both;
            visibility: hidden;
        }
        * html .columns {height: 1%;}
        .columns{ display:inline-block; }
        .columns{ display:block; }
        .columns .column{
          float:left;
          overflow:hidden;
          display:inline;
        }
        .columns .last{ float:right; }
    
        .col4 .first{ left: auto;width:25%; }
        .col4 .second{ left: auto;width:25%; }
        .col4 .third{ left: auto;width:25%; }
        .col4 .last{ left: auto;width:25%; }
        -->
    </style>

note: most of this stuff comes from this google result, I just adapted it to 4 columns.

The HTML then looks like this:

<div class="columns col4">
 <div class="column first”> SOME TEXT  </div><!-- /.first -—>
 <div class="column second”> MORE TEXT</div><!—- /.second -—>
 <div class="column third”> SOME MORE TEXT </div><!—- /.th开发者_运维问答ird -->
 <div class="column last”> SOME LAST TEXT </div><!-- /.last -—>
</div><!-- /.columns -->

Ok, I’ve simplified that a bit (there’s a small image and some < h2 > text in there too) but the thing is that I’d like to add some space between the columns. Here’s how it looks now:

Do you have any idea what CSS property should I touch?

note: If I add margin or padding, one column shifts down because (as I understand it) it doesn’t fit. There might be other CSSs as well, since this came in a template (I have been asked for this change, but I didn’t do any of this, as usual).

Thanks for any insight.

You need to add padding to the columns. But when you do that, you also need to subtract the same amount from the width property. This i because of the box-model.

.col4 .first{ left: auto;width:24%; padding-right:1% }
.col4 .second{ left: auto;width:24%; padding-right:1% }
.col4 .third{ left: auto;width:24%; padding-right:1% }
.col4 .last{ left: auto;width:24%; padding-right:1% }

inner margin = padding
