I wish to incorporate the colors shown in the Canvas style guide Canvas LMS but not clear on how to modify/embed the code into the HTML editor. In particular I wish to show different background colors for boxes constructed according to the Grid (flexboxgrid). With the help of a colleague I have managed to construct different grid designs but not clear on how to change the background colors according to the specifications shown in the style guide. Also if anybody has some creative ideas regarding changing other variables of the grid boxes (e.g. margins, borders etc.) and can show by example with codes or point me to some resources, would be much appreciated.
