Dynamic Goodreads SASS formatting

in programming on 18 January 2015

Summary

Putting up some code that might be useful to others when formatting Goodreads widgets using dynamic class creation in SASS.

Over at my reading list and book mini-reviews page, I've re-formatted the Goodreads widgets to save space and look a bit nicer. Originally was editing a bunch of CSS, but like other parts of the site, decided to migrate it over the SCSS. Below is the resulting code that allows me to compactly define the CSS stylesheet for all the different widgets. Since Goodreads javascript dynamically calls the html, I can't control the naming of the classes but they are similar across widgets that I can use @each loops, @extends (to define the actually styles) and lists to dynamically create all the CSS needed for that page. I used @extends instead of @include in this case because didn't need dynamic variables input to mixins and currently @include doesn't work with dynamic variables. The % signs are just placeholder selectors used in lieu of . and # normally seen with classes and ids.

See below for the code, useful either as a template for modifying your own SCSS or just as an example for nested @each loops in SCSS and combining them with @extends to dynamically define a group of classes easily.

sublime text

When coding, writing up blog post, or doing any other task, I generally have used Notepad++. It is a great program that au[...]tomatically detects, based on the extension, the type of code you are writing and parses the file accordingly. It is light and gets the job done, but it always felt like it could be taken to the next level. Enter Sublime Text 2, a program that seems to have everything I am looking for in a text editor and then some.
