Resizable div container attached to bottom in html.
I want to create a div that is sticky to the bottom and can appear when clicking the button that has height depending on the amount of text on the textarea. For example: Same like on sololearn non-html playground. When you type code on the editor and press "run", a window appears on the bottom that can be pulled up to resize and dismissed by pulling down. I wanted to make similar to that one. See my code and help me.. https://code.sololearn.com/WaTMzYI0f9iy/?ref=app
