I was creating a form where the person would have the option to choose a color, as I did not want the person to write the color or because I thought it cool I decided to put an input of the color type
<input type="color" name="cor" id="cor" class="cor">
But I do not know how I can modify it, it's kind of annoying to manipulate, I do not know if it's possible to leave it round or put a background url on it, I'd like to know how to tinker with it.
Using jQuery is also an option.
