title: How to create buttons and text enters with javascript in scripts. (Tampermonkey)
body: <p>Im creating scripts (Javascript) using tamper monkey. The most used scripts on this platform create buttons and boxes to enter text on the website they want the script to happen (for example creating an extra button on google.com and when clicked it does a function). I have a few examples like a you tube to mp4 converter thats directly on the youtube website itself. (If this helps) If this requires HTML or CSS In not really familiar with those languages.
  How do I create buttons and text boxes like this script to put into my JavaScript code?</p>
