How can i run a code using my phone to do it

Question

So that it can show in my browser

Answer 1

This only happens on your laptop or desktop monitor. Not your mobile

Answer 2

if using Chrome you can use
file:/// just type it into the url search area at the top of the page..and look for the file or folder. (as long as it's stored on device not the external storage.)
it depends on what kind of code your trying to run though. (html, etc.) if using python or something try termux and vim.

Answer 3

https://www.tutorialspoint.com/online_html_editor.php This is an online HTML compiler that you can write code and see it run on the web, either in desktop or mobile view. It works on a phone, I just tried it.
