Layout includes flexbox based responsive grid system with 12 columns.

Add the class columns to a container with the class container. And add any element you want with classname column inside the container. These columns will take up the space equally. You can specific the width of each column by adding class col-[1-12].

And you can add the class col-gapless to have gapless columns.

By default, Spectre grid has multi-line flexbox enabled. You can add the class col-oneline to columns to make all its child columns positioned in the same single row.

Spectre provides a neat responsive layout grid system. There are .col-xs-[1-12], .col-sm-[1-12], .col-md-[1-12], .col-lg-[1-12] and .col-xl-[1-12] available for flexible grid across mobile, tablet and desktop viewport usage.

• For window width less than 480px, all columns will show as a single row.

• col-sm-[1-12] apply to window width smaller than or equal to 600px.
