A simple, pure–CSS grid–system based on CSS–grid. This system allows for more complex layouts, using (for example) inline grids.


CSSGridSys is responsive, easy to tailor to your specific needs, very open and it supports the continuity of the grid, inside grid elements.


The basic syntax of CSSGridSys works as follows:


Where SCREEN_SIZE can be either s, m, l or xl and COL_SIZE can range from one to twelve (in words).

For example, an element that is 6 columns wide, would look like this:

<el class="s-col-six"></el>

These elements are nested inside a ‘grid’ parent-element, like so:

<parent class="grid s-col-six">
    <child class="s-col-six"></child>


Like you may be used to, CSSGridSys works with multiple definitions of screen-sizes and their respective column-sizes on the same element. If you want to create an element that is 6 columns wide on mobile sizes, and only 4 columns wide on desktop sizes, you can add up the classnames like so:

<el class="s-col-six m-col-four"></el>

This system can be applied to both parent and child elements, like so:

<parent class=“s-col-six m-col-twelve”>
    <child class=“s-col-six m-col-four”></child>
    <child class=“s-col-three m-col-four”></child>
    <child class=“s-col-three m-col-four”></child>

The above code block will result in a six-column main-grid on mobile sizes, containing a full-width and two half-width elements inside. On larger sizes, it will be a 12-column grid with 3 equally sized columns inside.

Inline grids

If your layout is slightly more complex or calls for parent elements defining interactions, CSSGridSys allows for inline grids that follow the original grid size by simply adding a “grid” class to any child-element, like so:

<grandparent class=“s-col-six”>
    <parent class=“s-col-four grid”>
          <child class=“s-col-three”>three column wide element</child>
          <child>one-column wide element</child>
    <parent class=“s-col-two”></child>


If you want to offset an element, you use the following basic syntax:


Where, again, SCREEN_SIZE can be either s, m, l or xl, and OFFSET_SIZE ranges from one to eleven (in words).

An element that is six columns wide, with an offset of 3 columns, would then look like so:

<el class=“s-col-six s-offset-three”></el>
You can’t perform that action at this time.
