I am using bootstrap and i find the height of the text field is too small.It\'s like less than 10px.I am wondering if it is small or i made some mistakes.

I used firebug

Answer 1

I don't know why if I open a clean new HTML5 page it works but after I add some code I don't know why it happens. So I just open the bootstrap.min.css file and search:type="text" and there there is height property and I change it to min-height for it have to be working.
