Baidu has AH (www.youa.com): (architecture is basically imitating Yui to do)
Body {

In the book "Beyond CSS," we recommend that we do the site to start resetting all default styles:
/* normalizes margin,padding */
BODY,DIV,DL,DT,DD,UL,OL,LI,H1,H2,H3,H4,H5,H6,PRE,FORM,FIELDSET,INPUT,P,BLOCKQUOTE,TH,TD {margin:0;padding:0}
/* normalizes font-size for headers */
H1,h2,h3,h4,h5,h6 {font-size:100%}
/* Removes List-style from lists */
Ol,ul {List-style:none}
/* normalizes font-size and font-weight to normal */
Address,caption,cite,code,dfn,em,strong,th,var {font-size:normal; Font-weight:normal}
/* Removes List-style from lists */
Table {border-collapse:collapse; border-spacing:0}
/* Removes border from fieldset and IMG */
fieldset,img {border:0}
/* left-aligns text in caption and th */
caption,th {Text-align:left}
/* Removes quotation marks from Q */
Q:before,q:after {content: '}
So what do we do with CSS reset when we actually write code?
I personally recommend using the CSS Reset (Eric Meyer and Yui)
Eric Meyer ' s Reset:
HTML, body, Div, span, applet, object, IFRAME,
H1, H2, H3, H4, H5, H6, p, blockquote, Pre,
A, ABBR, acronym, address, big, cite, code,
Del, DFN, EM, Font, IMG, ins, KBD, Q, S, Samp,
Small, strike, strong, sub, SUP, TT, VAR,
b, u, I, center,
DL, DT, DD, OL, UL, Li,
FieldSet, form, label, legend,
Table, Caption, Tbody, TFOOT, THEAD, tr, TH, TD {
margin:0;
padding:0;
border:0;
outline:0;
font-size:100%;
Vertical-align:baseline;
Background:transparent;
}
Body {
Line-height:1;
}
OL, UL {
List-style:none;
}
BLOCKQUOTE, Q {
Quotes:none;
}
Blockquote:before, Blockquote:after,
Q:before, Q:after {
Content: ";
Content:none;
}
/* Remember to define focus styles! */
: Focus {
outline:0;
}
/* Remember to highlight inserts somehow! */
INS {
Text-decoration:none;
}
del {
Text-decoration:line-through;
}
/* Tables still need ' cellspacing= "0" ' in the markup * *
Table {
Border-collapse:collapse;
border-spacing:0;
}
YUI:
BODY,DIV,DL,DT,DD,UL,OL,LI,H1,H2,H3,H4,H5,H6,PRE,FORM,FIELDSET,INPUT,TEXTAREA,P,BLOCKQUOTE,TH,TD {
margin:0;
padding:0;
}
Table {
Border-collapse:collapse;
border-spacing:0;
}
fieldset,img {
border:0;
}
Address,caption,cite,code,dfn,em,strong,th,var {
Font-style:normal;
Font-weight:normal;
}
Ol,ul {
List-style:none;
}
caption,th {
Text-align:left;
}
H1,h2,h3,h4,h5,h6 {
font-size:100%;
Font-weight:normal;
}
Q:before,q:after {
Content: ";
}
abbr,acronym {border:0;
}
Combined with their CSS reset, and then according to their actual situation, will be able to write the perfect CSS reset in line with their own website.
