Question 44207 in Html Question posted in
Some basic documentation can be found here.

Why is there no style on my angular material component – Html

Why does my expansion panel and form fields have no style or functionality?

I have imported the module and imported angular theme in my style.scss.

MatIcon and the other components I have tested don’t seem to work at all either.

Here is all the code I could think to include, any help would be appreciated!

Bugged expansion panel:

I also get this error when I attempt to open/close the expansion panel:

    I found a solution eventually. I deleted the project and started a new one. Steps I followed to avoid error:

    ng new [project-name]
cd [project-name]
npm install
ng add @angular/material

    then I went into package.json and changed the cdk and material versions to 14.0.0

    npm install
ng add @angular/material

  2. 0

    In your dependencies, you’re trying to use Angular Material 7 with Angular 14. Try Angular material 14 instead. Also, scss import should be:

    @import "~@angular/material/theming";
