You don't really care how admin panel looks like, yeah?
Bootstrap allows you to create not-so-ugly UI elements but you still have to assemble them into templates.
But there's some free admin themes for bootstrap that are already designed.
Browsers are so smart they are trying to fill forms for you. And sometimes this is bad.
Html5 provides an attribute
autocomplete="on|off" to prefent browsers filling fields for you. And you should add
autocomplete="off" to inputs in cases like these:
- "Set password", "Change password" and "Retype password" fields.
- Captcha field.
- Credit card number.
Sometimes you need to do it for security reasons. Sometimes it just makes your forms more comfortable.
