This job will have you editing and updating CSS/JS/HTML files for a webapp to have certain UX/design behaviours happen (or stop happening)
Top notch CSS/HTML is essential.
While you won't be required to do any logic based JS ( Ajax, Data manip , etc..) be mindful that you will be required from time to time to use JS to enable certain UX behaviours you can't accomplish using CSS solely.
Examples of some tasks you WILL be doing:
-Be given CSS/HTML/JS files and asked to make certain CSS behaviours. Eg: 'Make elements in a page transition to a different location then load using animation X page Y when button Z is clicked.' . You will be responsible for taking the mandate and coding the necessary CSS and possibly JS required to make it happen.
-Make plugins play nice aesthetically. Example Given some jQuery visual library that manipulates the DOM , you will be asked to make it play nice with Boostrap 3
-Track, debug and Fix some current CSS bugs and UX behaviours...
