Answer 1

It's different regarding which browser, thus if you want a pixel-perfect design then practice is to "reset" those values to 0 (margin and padding) and set them yourself.

"CSS reset" is very common to front-end developers, a simple example of one i use :

html,body,blockquote,code,h1,h2,h3,h4,h5,h6,p,pre{margin:0;padding:0}
button,fieldset,form,input,legend,textarea,select{margin:0;padding:0}
fieldset{border:0}
a,a *{cursor:pointer}
div{margin:0;padding:0;background-color:transparent;text-align:left}
hr,img{border:0}
applet,iframe,object{border:0;margin:0;padding:0}
button,input[type=button],input[type=image],input[type=reset],input[type=submit],label{cursor:pointer;}
ul,li{list-style:none;margin:0;padding:0;}
strong{font-weight:bold;}
em{font-style:italic;}
