base.css(css基础样式)
1、全面base.css
@charset "utf-8"; /* CSS Document */ @charset "utf-8"; /*! * @名称:base.css * @功能:1、重设浏览器默认样式 * 2、设置通用原子类 */ /* 防止用户自定义背景颜色对网页的影响,添加让用户可以自定义字体 */ html { background:white; color:black; } /* 内外边距通常让各个浏览器样式的表现位置不同 */ body,div,dl,dt,dd,ul,ol,li,h1,h2,h3,h4,h5,h6,pre,code,form,fieldset,legend,input,textarea,p,blockquote,th,td,hr,button,article,aside,details,figcaption,figure,footer,header,hgroup,menu,nav,section { margin:0; padding:0; } /* 要注意表单元素并不继承父级 font 的问题 */ body,button,input,select,textarea { font:12px \5b8b\4f53,arial,sans-serif; } input,select,textarea { font-size:100%; } /* 去掉 table cell 的边距并让其边重合 */ table { border-collapse:collapse; border-spacing:0; } /* ie bug:th 不继承 text-align */ th { text-align:inherit; } /* 去除默认边框 */ fieldset,img { border:none; } /* ie6 7 8(q) bug 显示为行内表现 */ iframe { display:block; } /* 去掉 firefox 下此元素的边框 */ abbr,acronym { border:none; font-variant:normal; } /* 一致的 del 样式 */ del { text-decoration:line-through; } address,caption,cite,code,dfn,em,th,var { font-style:normal; font-weight:500; } /* 去掉列表前的标识,li 会继承 */ ol,ul { list-style:none; } /* 对齐是排版最重要的因素,别让什么都居中 */ caption,th { text-align:left; } /* 来自yahoo,让标题都自定义,适应多个系统应用 */ h1,h2,h3,h4,h5,h6 { font-size:100%; font-weight:500; } q:before,q:after { content:‘‘; } /* 统一上标和下标 */ sub,sup { font-size:75%; line-height:0; position:relative; vertical-align:baseline; } sup { top:-0.5em; } sub { bottom:-0.25em; } /* 让链接在 hover 状态下显示下划线 */ a:hover { text-decoration:underline; } /* 默认不显示下划线,保持页面简洁 */ ins,a { text-decoration:none; } /* 去除 ie6 & ie7 焦点点状线 */ a:focus,*:focus { outline:none; } /* 清除浮动 */ .clearfix:before,.clearfix:after { content:""; display:table; } .clearfix:after { clear:both; overflow:hidden; } .clearfix { zoom:1; /* for ie6 & ie7 */ } .clear { clear:both; display:block; font-size:0; height:0; line-height:0; overflow:hidden; } /* 设置显示和隐藏,通常用来与 js 配合 */ .hide { display:none; } .block { display:block; } /* 设置浮动,减少浮动带来的 bug */ .fl,.fr { display:inline; } .fl { float:left; } .fr { float:right; }
2、常用base.css
@charset "utf-8"; /* CSS Document */ body, ul, ol, dl, li, dd, h1, h2, h3, h4, h5, h6, p, input { margin: 0 } h1, h2, h3, h4, h5, h6 { font-size: 100%; font-weight: normal; font-family: "Microsoft YaHei"; } img { border: none } input, button, textarea, select { *font-size: 100%; border: none; } body { background: #fff; color: #5e5e5e; font: 14px/24px Microsoft YaHei, SimSun, Arial; } ul, ol { list-style: none; padding: 0 } table { border-collapse: collapse; border-spacing: 0 }/*默认a标签样式*/ a:link, a:visited { color: #5e5e5e; text-decoration: none; } a:hover { /*color:#999;*/ } a:hover { color: #c9394a; /*text-decoration: underline;*/ } a:active { color: #666; }/*浮动和清除浮动*/ .fl { float: left } .fr { float: right } .clear { zoom: 1 } .clear:after { content: ""; display: block; height: 0; visibility: visible; clear: both } /*显示隐藏*/ .hide { display: none } .show { display: block }/*表格table和td有边框*/ .boder_tl { border-top: 1px solid #ccc; border-left: 1px solid #ccc; } .boder_tl td { border-bottom: 1px solid #ccc; border-right: 1px solid #ccc; } .boder_bl { border-bottom: 1px solid #ccc; border-left: 1px solid #ccc; } .boder_bl td { border-top: 1px solid #ccc; border-right: 1px solid #ccc; } .boder_tr { border-top: 1px solid #ccc; border-right: 1px solid #ccc; } .boder_tr td { border-bottom: 1px solid #ccc; border-left: 1px solid #ccc; } .boder_br { border-bottom: 1px solid #ccc; border-right: 1px solid #ccc; } .boder_br td { border-top: 1px solid #ccc; border-left: 1px solid #ccc; } .txt_center { text-align: center; }/*表格table和tr有边框*/ .boder_ltr_trborder { border: 1px solid #ccc; border-bottom: none; } .boder_ltr_trborder tr { border-bottom: 1px solid #ccc; }
