A simple Responsive grid system

Download View on GitHub


Gridious is a simplistic CSS grid framework that is fully responsive and customizable. You can easily add to or edit the existing code to fit your individual project needs. It was created as a simple, bloat-free alternative to Bootstrap, Foundation, and the various other frameworks out there and was modelled off of the grid features I found to be most effective while working with them. In addition, I wanted to create a grid system that I could easily adapt to each project I work on.

Installation & Setup

All the installation that is required is simply including the compiled CSS file in your document and Gridious will now be available on every page it is included on.


There are a number of configuration options you can adjust if you like (or just leave the defaults). They can be found in _config.scss

Property Variable Name Description Default
Small Breakpoint $sm-break The upper limit of the small screen size 480px
Medium Breakpoint $md-break The upper limit of the medium screen size 959px
Max Width $max-width The max width the grid will expand for 1200px
Column Number $column-number The number of columns per row 12
Gutter $column-padding The space on either side of each column 15px

The Grid

The grid is easy to use and has 3 main screen sizes (unless otherwise edited). They are:

@media only screen and (max-width: 480px) {
    // Small Screen
    // Syntax: sm-col-X where X is an integer between 1 and $column-number

@media only screen and (max-width: 481px) and (max-width: 959px) {
    // Medium Screen
    // Syntax: md-col-X where X is an integer between 1 and $column-number

@media only screen and (min-width: 960px) {
    // Large Screen
    // Syntax: lg-col-X where X is an integer between 1 and $column-number

Gridious is mobile-first and you may have different columns for each screen size. If the total number of columns in a row exceeds the max number of columns set (Default: 12), it will wrap below.


Utility Classes

There are a couple of utility classes that can be used in conjunction with the grid by adding the classes to elements.

Name Description Usage
Full Width Allows the row to span the entire width, ignoring the max width set in config .gd-full
Clearfix Clearfix hack; fixes floating issues that sometimes occurs .clearfix
Hide All Screens Hides an element on any screen size .gd-hide
Hide on Small Only Hides an element when on small screen .gd-hide-sm
Hide on Medium Only Hides an element when on medium screen .gd-hide-md
Hide on Medium & Down Hides an element when on medium screen or below .gd-hide-md-down
Hide on Medium & Up Hides an element when on medium screen or above .gd-hide-md-up
Hide on Large Only Hides an element when on large screen .gd-hide-lg

Add additional utility classes of your own in _utilities.scss if you wish.


Gridious is simple to use and edit. It is a barebones CSS framework and, as a result, you can easily customize to fit whatever project you happen to be working on. The files included and their usages are as follows:

File Name Usage
_config.scss Holds all configuration variables
_grid.scss Where the grid functionality is stored
_mixins.scss Holds mixins used in other files
_utilities.scss Holds all utility classes
_variables.scss Holds and defines all variables used in other files

If you wish to add another screen size, you can take advantage of the generate-columns mixin:

        // --- Generate Columns ---
        // $size is the column name/size (ex: sm, md, lg)
        @mixin generate-column($size) {
            @for $sizeName from 1 through $columns {
                .#{$size}-col-#{$sizeName} {
                    width: (100%/($columns/$sizeName));

In addition to the mixin, you can also create an type of column you wish as long as the collective widths add to 100%. For example,
