how to apply a class to multiple inputs?

Question

class="inputstyle"
<input type=text id="username" placeholder="enter username">
<input type=.....>
<input type=blahaahahah>

Answer 1

You can define style for input:

input{
background : #222;
}

Similar for textarea if you have it in your form. Like for any other stuff. You can combine it with :focus to set additional visual enhancements.
