Generate me an website in a modern smooth style with custom script selection, market-like, an placeholder image background on top 1/3 of the added script - image of purple grids canvas taken from an angle, rest 2/3 should be an static colour. there should be an icon to edit, also purple-bluelish color, you may use font awesome for icons. On the top bar there should be buttons like create that will open up a form dialogue asking for name, description and an button to finally add it. After topbar there comes the main menu with the created scripts as told above.
