The reset function of the CSS reset (desirable or not, depending on you)

I. Reasons for the Reset

In today's popular browser, some of them are in their own way to understand the CSS specification, this will be only the browser to the CSS interpretation and the designer's CSS definition of the original intention of the conflict, so that the appearance of the Web page in some browsers can be correctly displayed according to the designer's ideas. But some browsers don't show up as the designers want them to, which leads to browser compatibility issues

So, by resetting the CSS property of the button tag and then defining it uniformly, you can produce the same display effect

　　The role of CSS Reset is to make each browser CSS style has a unified benchmark, and this benchmark is more "clear 0"!

The following is a full section of CSS Reset's style reset information displayed:

1 html, body, Div, span, object, IFRAME,2 H1, H2, H3, H4, H5, H6, p, blockquote, Pre,3 abbr, address, cite, code,4 del, DFN, EM, img, INS, KBD, Q, Samp,5 small, strong, sub, SUP, VAR,6 B, I,7 DL, DT, DD, OL, UL, Li,8 fieldset, form, label, legend,9 table, Caption, Tbody, TFOOT, THEAD, tr, TH, TD,Ten article, aside, canvas, details, figcaption, figure, One footer, Header, Hgroup, menu, nav, section, summary, A Time , mark, audio, video{ - margin:0; - padding:0; the Border:0; - Outline:0; - font-size:100%; - vertical-align:Baseline; + background:Transparent; -} +  A Body{ at Line-height:1; -} -  - : Focus{ - Outline:1; -} in  - Article,aside,canvas,details,figcaption,figure, to footer,header,hgroup,menu,nav,section,summary{ + Display:Block; -} the  * Nav ul{ $ List-style:None;Panax Notoginseng} -  the blockquote, Q{ + Quotes:None; A} the  + Blockquote:before, Blockquote:after, - Q:before, Q:after{ $ content:"'; $ content:None; -} -  the a{ - margin:0;Wuyi padding:0; the Border:0; - font-size:100%; Wu vertical-align:Baseline; - background:Transparent; About} $  - ins{ - Background-color:#ff9; - Color:#000; A text-decoration:None; +} the  - Mark{ $ Background-color:#ff9; the Color:#000; the Font-style:Italic; the Font-weight:Bold; the} -  in del{ the text-decoration:Line-through; the} About  the Abbr[title], Dfn[title]{ the Border-bottom:1px dotted #000; the cursor: Help; +} -  the Table{Bayi Border-collapse:collapse; the border-spacing:0; the} -  - HR{ the Display:Block; the Height:1px; the Border:0; the Border-top:1px solid #cccccc; - margin:1em 0; the padding:0; the} the 94 input, select{ the vertical-align:Middle; the}

For the above code, I do the following several notes:

1. This part is for the browser part of the CSS to reset, personally think not all the code is required to do so, after all, there are many tags in the process of writing your page does not necessarily use

2. According to their actual situation to choose the appropriate code to use, do not copy, this is the experience summed up by predecessors

The above code can also be simplified into the following code form:

1 body, DL, DD, H1, H2, H3, H4, H5, H6, p, form {2    margin:0;  34  ol,ul{5    margin:0;  6    padding:0;  7 }

According to the actual situation reasonable use of the relevant reset code, because if your CSS file itself is relatively large, add the relevant reset code will also make your CSS file larger point, for the company, this is not access to!!!
