CSS--填坑經常使用代碼分享

如下是經常使用的代碼收集，沒有任何技術含量，只是填坑的積累。

一. css 2.x code

1. 文字換行

/*強制不換行*/ white-space:nowrap; /*自動換行*/ word-wrap: break-word; word-break: normal; /*強制英文單詞斷行*/ word-break:break-all; 

2. 兩端對齊

text-align:justify;text-justify:inter-ideogra 

3. 去掉Webkit(chrome)瀏覽器中input(文本框)或textarea的黃色焦點框

input,button,select,textarea{ outline:none;} textarea{ font-size:13px; resize:none;}

去掉chrome記住密碼後自動填充表單的黃色背景

4. ie6: position:fixed

.fixed-top /* position fixed Top */{position:fixed;bottom:auto;top:0; } * html .fixed-top /* IE6 position fixed Top */{position:absolute;bottom:auto;top:expression(eval(document.documentElement.scrollTop));} *html{background-image:url(about:blank);background-attachment:fixed;} 

5. clearfix

.clearfix:after{visibility:hidden;display:block;font-size:0;content:" ";clear:both;height:0;} .clearfix{display:inline-block;} html[xmlns] .clearfix{display:block;} * html .clearfix{height:1%;} .clearfix{*zoom: 1;} .clearfix:after{clear:both;display:table;content:"」;} .clearfix{overflow:hidden;_zoom:1;}

6. seperate-table

.tab{border-collapse:separate;border:1px solid #e0e0e0;} .tab th,.tab td{padding:3px;font-size:12px;background:#f5f9fb;border:1px solid;border-color:#fff #deedf6 #deedf6 #fff;} .tab th{background:#edf4f0;} .tab tr.even td{background:#fff;} 

<table class="tab" width="100%" cellpadding="0" cellspacing="0" border="0"> <tr> <th>111</th> <td>222</td> </tr> <tr> <th>111</th> <td>222</td> </tr> </table> 

7. 光標大小：

8. min-height: 最小高度兼容代碼

.minheight500{min-height:500px;height:auto !important;height:500px;overflow:visible;} 

9. 鼠標不容許點擊：

cursor:not-allowed; 

10. mac font: osx平臺字體優化

font-family:"Hiragino Sans GB","Hiragino Sans GB W3",'微軟雅黑'; 

11. 省略號：

.ellipsis{white-space:nowrap;overflow:hidden;text-overflow:ellipsis} 

二. css3 code

1. 漸變：

.a{background:-webkit-gradient(linear,left top,left bottom,from(#69bdf9),to(#4aa7e8));background:-moz-linear-gradient(top,#67bcf8,#3b96d6);background:-o-linear-gradient(top,#67bcf8,#3b96d6);background:linear-gradient(top,#67bcf8,#3b96d6);} 

2.投影：

.b{box-shadow:inset 1px -1px 0 #f1f1f1;text-shadow:1px 1px 0px #630;} filter:progid:DXImageTransform.Microsoft.gradient(enabled='true',startColorstr='#99000000',endColorstr='#99000000');background:rgba(0,0,0,.6); background:rgba(0,0,0,0.5);filter:progid:DXImageTransform.Microsoft.gradient(GradientType=0,startColorstr='#50000000',endColorstr='#50000000')\9; 

看哪一個startColorstr和endColorstr，一共8位，後6位是RGB的顏色代碼，前兩位是16進制的

好比60%透明，就是256x0.6=154，再換算成16進制=9A
background-image:-ms-linear-gradient(top, #fff, #ddd); ie10漸變

16進制的轉換

透明兼容

3. search佔位

http://www.qianduan.net/search-box-style-custom-webkit.html

::-webkit-input-placeholder {}
::-moz-input-placeholder {}
input:focus::-webkit-input-placeholder { color: transparent; }
-webkit-appearance:none;  google邊框去除
input[type="search"]{-webkit-appearance:textfield;} // 去除chrome默認樣式 http://i.wanz.im/2011/02/04/remove_border_from_input_type_search/ http://blog.csdn.net/do_it__/article/details/6789699 line-height: normal; /* for non-ie */ line-height: 22px\9; /* for ie */ 

4.

title 換行：
 

5. 漸變

background: #bde25e; /* Old browsers */ background: -moz-linear-gradient(top, #bde25e 2%, #8bb31d 100%); /* FF3.6+ */ background: -webkit-gradient(linear, left top, left bottom, color-stop(2%,#bde25e), color-stop(100%,#8bb31d)); /* Chrome,Safari4+ */ background: -webkit-linear-gradient(top, #bde25e 2%,#8bb31d 100%); /* Chrome10+,Safari5.1+ */ background: -o-linear-gradient(top, #bde25e 2%,#8bb31d 100%); /* Opera 11.10+ */ background: -ms-linear-gradient(top, #bde25e 2%,#8bb31d 100%); /* IE10+ */ background: linear-gradient(to bottom, #bde25e 2%,#8bb31d 100%); /* W3C */ filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#bde25e', endColorstr='#8bb31d',GradientType=0 ); /* IE6-9 */  @media screen and (max-width:1220px) and (min-width:1151px) { #wrapper {font-size:15px;} }

CSS 實現 textArea 的 placeholder 換行

6.阻止默認事件

pointer-events:none; 

7. 變灰 gray:

html{ filter: grayscale(100%); -webkit-filter: grayscale(100%); -moz-filter: grayscale(100%); -ms-filter: grayscale(100%); -o-filter: grayscale(100%); filter: url("data:image/svg+xml;utf8,<svg xmlns=\'http://www.w3.org/2000/svg\'><filter id=\'grayscale\'><feColorMatrix type=\'matrix\' values=\'0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0 0 0 1 0\'/></filter></svg>#grayscale"); filter:progid:DXImageTransform.Microsoft.BasicImage(grayscale=1); -webkit-filter: grayscale(1); } 

8. firefox 阻止選中：

-moz-user-focus:ignore;-moz-user-input:disabled;-moz-user-select:none; 

9. 箭頭

display:block;border:solid transparent;line-height: 0;width:0; height:0;border-top:solid #0288ce;border-width:8px 6px 0 6px; border-style:solid; border-width:7px; border-color:transparent transparent transparent #ff7020; 

ie6 bug測試，把border-style設爲dashed.

10. 取消textarea右下角可拖動手柄：

resize:none 

11. 取消chrome form表單的聚焦邊框：

input,button,select,textarea{outline:none} textarea{resize:none} 

12. 取消a連接的黃色邊框：

a{-webkit-tap-highlight-color:rgba(0,0,0,0);} 

13. 漸變

filter: progid:DXImageTransform.Microsoft.gradient(GradientType=0, startColorstr=#ef6464, endColorstr= #eb4141);/*IE<9>*/ -ms-filter: "progid:DXImageTransform.Microsoft.gradient (GradientType=0, startColorstr=#ef6464, endColorstr=#eb4141)";/*IE8+*/ 

14.chrome字體縮小:

.chrome_adjust { font-size: 9px; -webkit-transform: scale(0.75); } 

15. webkit 水平居中：

display:-webkit-box;-webkit-box-pack:center; -webkit-box-align: center; 

16. 取消chrome 搜索x提示：

input[type=search]::-webkit-search-decoration, input[type=search]::-webkit-search-cancel-button, input[type=search]::-webkit-search-results-button, input[type=search]::-webkit-search-results-decoration { display: none; } 

17. autofill:

http://stackoverflow.com/questions/2338102/override-browser-form-filling-and-input-highlighting-with-html-css

input:-webkit-autofill {-webkit-box-shadow: 0 0 0px 1000px white inset;} input:-webkit-autofill, textarea:-webkit-autofill, select:-webkit-autofill { -webkit-box-shadow: 0 0 0 1000px white inset; } autocomplete="off" 

18. 手機版本網頁a標記虛線框問題

a:focus { outline:none; -moz-outline:none; } 

19. 焦點去除背景：

-webkit-tap-highlight-color: rgba(255, 255, 255, 0); -webkit-tap-highlight-color: transparent; // i.e. Nexus5/Chrome and Kindle Fire HD 7'' 

20. placeholder佔位符顏色自定義

input:-moz-placeholder { color: #369; } ::-webkit-input-placeholder { color:#369; }
