[html] How create table only using <div> tag and Css

In building a custom set of layout tags, I found another answer to this problem. Provided here is the custom set of tags and their CSS classes.

HTML

<layout-table>
   <layout-header> 
       <layout-column> 1 a</layout-column>
       <layout-column>  </layout-column>
       <layout-column> 3 </layout-column>
       <layout-column> 4 </layout-column>
   </layout-header>

   <layout-row> 
       <layout-column> a </layout-column>
       <layout-column> a 1</layout-column>
       <layout-column> a </layout-column>
       <layout-column> a </layout-column>
   </layout-row>

   <layout-footer> 
       <layout-column> 1 </layout-column>
       <layout-column>  </layout-column>
       <layout-column> 3 b</layout-column>
       <layout-column> 4 </layout-column>
   </layout-footer>
</layout-table>

CSS

layout-table
{
    display : table;
    clear : both;
    table-layout : fixed;
    width : 100%;
}

layout-table:unresolved
{
    color : red;
    border: 1px blue solid;
    empty-cells : show;
}

layout-header, layout-footer, layout-row 
{
    display : table-row;
    clear : both;   
    empty-cells : show;
    width : 100%;
}

layout-column 
{ 
    display : table-column;
    float : left;
    width : 25%;
    min-width : 25%;
    empty-cells : show;
    box-sizing: border-box;
    /* border: 1px solid white; */
    padding : 1px 1px 1px 1px;
}

layout-row:nth-child(even)
{ 
    background-color : lightblue;
}

layout-row:hover 
{ background-color: #f5f5f5 }

The key to getting empty cells and cells in general to be the right size, is Box-Sizing and Padding. Border will do the same thing as well, but creates a line in the row. Padding doesn't. And, while I haven't tried it, I think Margin will act the same way as Padding, in forcing and empty cell to be rendered properly.
