Foreach in Sass

sass

Recently I had a website to build which had different sectors, and each sector had a different colour association.

for example:

  • section 1 : red
  • section 2 : blue
  • section 3 : green

Normally I would write out each css style, something like this:

.red .section-background-color{ backgroud-color : #CF0A2C; ..etc } .blue .section-background-color{ background-color : #6CAAE4; ..etc } ...etc

#Using sass Since I was using sass this was made easier.

First I declared my colour variables: $blue : (blue, #6CAAE4) $red : (red, #CF0A2C)

Then I ran a loop: @each $color in $blue, $red $name : nth($color, 1) $val : nth($color, 2) .#{name} .section-background-color background-color : val

In total I had about 8 different colours, each requiring a different background colour and text-color declaration.

I soon built up a little collection of classes I could use through out the project. In order to change the colour of a page all i would need to do is change the parent class and the colour scheme would change accordingly.

If you have a better way of doing this let me know over twitter @millard_
