CSS存在Bug,但怎么能让我们记住这些Bug,以便在以后编写CSS代码的时候能很好的应对,这不,有心人就编写了这么一个CSS BUG顺口溜,还是挺不错的:
一、IE边框若显若无,须注意,定是高度设置已忘记;
二、浮动产生有缘故,若要父层包含住,紧跟浮动要清除,容器自然显其中;
三、三像素文本慢移不必慌,高度设置帮你忙;
四、兼容各个浏览须注意,默认设置行高可能是杀手;
五、独立清除浮动须铭记,行高设无,高设零,设计效果兼浏览;
六、学布局须思路,路随布局原理自然直,轻松驾驭html,流水布局少hack,代码清爽,兼容好,友好引擎喜欢迎。
七、所有标签皆有源,只是默认各不同,span是无极,无极生两仪—内联和块级,img较特殊,但也遵法理,其他只是改造各不同,一个*号全归原,层叠样式理须多练习,万物皆规律。
八、图片链接排版须小心,图片链接文字链接若对齐,padding和vertical-align:middle要设定,虽差微细倒无妨。
九、IE浮动双边距,请用display:inline拘。
十、列表横向排版,列表代码须紧靠,空隙自消须铭记。
怎么样,是不是心里清楚了一些,至少来说以后对编写CSS有帮助的。
