Globally toggle css classes?












0














I have some CSS that outlines every div in red. I use it for debugging to see how elements are aligning.



I have a button that currently toggles a bunch of debugging features on my app. I'd like to incorporate the toggling of my red outlines as well.



How would I go about toggling these classes considering I'm using angular and the angular cli? I'd like to avoid dynamically loading and unload the style sheet if at all possible.

You can take an inspiration from Angular Material site itself. If you visit the URL, the top bar in the site gives you an option to change the theme. On the similar lines, you can have a CSS dedicated for debug and normal mode each. The debug mode will enable the effect you desire. Under the hood, the Material code does following things.




  1. Maintains a list of CSS style list. Search for themes variable in
    srcappsharedtheme-pickertheme-picker.ts file.


  2. Depending on the option selected by a user, it invokes setStyle method
    of StyleManager (available in
    srcappsharedstyle-managerstyle-manager.ts).


  3. A link href tag in HTML head section is manipulated by
    style-manager.



This definitely seems to be a much cleaner approach. The source code of the site can be accessed here.
