Code editor error. Alert

When I am in the editor there is a problem. Sometimes the keyboard doesn’t type anything. And it doesn’t erase either. It’s as if it went into a non-typing mode. And the tags are put inside black borders. And I have already tried on different devices.

Welcome, germanibenitezalfons.

If you are using a mobile device, the default keyboard does not always play well with the freeCodeCamp editor. I recommend you read the article on using a mobile device to view some tips - most importantly, check out the coding keyboards listed as they interface with the editor well.

Hope this helps
