Grasshopper Suggestion

I Suggest That To Have HTML, CSS Course in The Grasshopper App. Because I Have A Slow Internet Connection, I Really Want To Learn It. And is There Any Suggestion That I Have To Know And Agree. Because i am Really Curious.

You can’t learn coding with grasshopper on the webpage?

I Can;t Because My Internet is Too Slow For The Web Page And Of Course, I Can’t Log in With My Account. As I Always Saw about:blank Page Disappears every 10 seconds After Clicking Sign up With Google.
