上个星期,制定的前端开发规范,今天抽查了css规范的执行;发现了很多问题

引入了css 模块化思想,可以接受少量的代码冗余,但不表示可以接受大面积的代码冗余。

表现症状1

.footer .home-icon:before{background-position:1px -166px;width: 42px;height: 40px;margin: 8px 0 2px}.footer .productList-icon:before{background-position:-45px -166px;width: 42px;height: 40px;margin: 8px 0 2px}.footer .me-icon:before{background-position:-89px -166px;width: 42px;height: 40px;margin: 8px 0 2px}.footer .mores-icon:before{background-position:-135px -166px;width: 42px;height: 40px;margin: 8px 0 2px}.footer .homeActive:before{background-position:1px -210px;width: 42px;height: 40px;margin: 8px 0 2px}.footer .productListActive:before{background-position:-45px -210px;width: 42px;height: 40px;margin: 8px 0 2px}.footer .meActive:before{background-position:-89px -210px;width: 42px;height: 40px;margin: 8px 0 2px}.footer .moresActive:before{background-position:-135px -210px;width: 42px;height: 40px;margin: 8px 0 2px}

上面的代码就范了大面积冗余的问题;

42px;height: 40px;margin: 8px 0 2px 这些代码都是一样的,完全可以把它们定义成一个。

.footer .icons:before{width: 42px;height: 40px;margin: 8px 0 2px}.footer .home-icon:before{background-position:1px -166px}.footer .productList-icon:before{background-position:-45px -166px}.footer .me-icon:before{background-position:-89px -166px}.footer .mores-icon:before{background-position:-135px -166px}.footer .homeActive:before{background-position:1px -210px}.footer .productListActive:before{background-position:-45px -210px}.footer .meActive:before{background-position:-89px -210px}.footer .moresActive:before{background-position:-135px -210px}

表现症状2

.property .regular-module1 .append-list{width: 100%;height: 90px;background-color: #FFF;}.property .regular-module1 .append-list .append-listData{display: inline-block;width: 88%;height: 90px}.property .regular-module1 .append-list .append-listData .append-word1{font-size: 24px;color: #666;padding-top: 18px;clear: both}.property .regular-module1 .append-list .append-listData .append-word2{font-size: 20px;color: #999;padding-top: 10px;clear: both}.property .regular-module1 .append-list .append-listData .append-wordData1{float: left;padding-left: 30px;}.property .integralDetails-module1 .append-list{width: 100%;height: 90px;background-color: #FFF;}.property .integralDetails-module1 .append-list .append-listData{display: inline-block;width: 100%;height: 90px}.property .integralDetails-module1 .append-list .append-listData .append-word1{font-size: 24px;color: #666;padding-top: 18px;clear: both}.property .integralDetails-module1 .append-list .append-listData .append-word2{font-size: 20px;color: #999;padding-top: 10px;clear: both}.property .integralDetails-module1 .append-list .append-listData .append-wordData1{float: left;padding-left: 30px;}

上列中,虽然分了模块,但事实上引入了3层的模块嵌套,我们完全没有必要这样做,完全可以简化成下面的内容,不仅css文件减少了,而且代码也更简洁;如果有差异,在增加一个样式嵌套就可以了,所以,一般只要3层嵌套就可以解决大部分的样式问题,模块实在太大,css太多,完全可以分拆成2个模块来实现。

.property .append-list{width: 100%;height: 90px;background-color: #FFF;}.property .append-listData{display: inline-block;width: 88%;height: 90px}.property .append-word1{font-size: 24px;color: #666;padding-top: 18px;clear: both}.property .append-word2{font-size: 20px;color: #999;padding-top: 10px;clear: both}.property .append-word-data1{float: left;padding-left: 30px;}

有些规范被忽略了

超过3层嵌套

.property .regular-module1 .append-list .append-listData{display: inline-block;width: 88%;height: 90px}.property .regular-module1 .append-list .append-listData .append-word1{font-size: 24px;color: #666;padding-top: 18px;clear: both}.property .regular-module1 .append-list .append-listData .append-word2{font-size: 20px;color: #999;padding-top: 10px;clear: both}.property .regular-module1 .append-list .append-listData .append-wordData1{float: left;padding-left: 30px;}.property .regular-module1 .append-list .append-listData .append-wordData2{float: right}.property .regular-module1 .append-list .append-listData .append-wordData3{color: #ff6046}.property .regular-module1 .append-list .append-listIcon{display: inline-block;margin-bottom: 32px}

规范定义css嵌套尽量在3层以内,上列尽量有5层嵌套,并且还有一个问题是,样式的命名采用了部分驼峰方式。

没有使用-线连接

使用了单词命名css

.more{float: right;margin: 0 20px;}.more:before{background-position:-116px 3px;width: 30px;height: 30px;margin-bottom: -7px}.eye,.eyes{float: right;display: inline-block;margin: 0 30px;}.eye:before{background-position:-240px 14px;width: 32px;height: 24px;}.eyes:before{background-position:-240px -12px;width: 32px;height: 24px;}
