I am currently building my first website in Laravel. In the past I've just done WordPress. I was surprised at how much work went into styling the forms, both of general aesthetics and accessibility.

A great tip was to use an appropriately colored shadow for focus and errors in the forms. It improved legibity a lot.

User agents usually do this. This Basic.css demo does show an outline for Chrome and Safari, but not Firefox... odd, because that does appear if I remove Basic.css stylesheet.
