篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了html+css仿制小米商城首页相关的知识,希望对你有一定的参考价值。
一、首先是学习心得
简介:
这是一个仅用css+html实现的页面,不过y页面也用css实现了一些精致的动态效果,比如
- 老版本小米官网的logo滑动效果
- 小米的二维码和购物车,导航栏延时下拉效果
关于一些css常用的进阶知识
-
box-shodow
-
display的几种用法 除了常见的块元素和行内元素的切换,还有行内块的概念,更有使用display:none隐藏块元素,通过伪类:hover去修改可视性,提到的display:none,就不得不说它与visibility: hidden的区别,设置了display: none,那么该元素以及它的所有后代元素都会隐藏,隐藏后的元素无法点击,占据的空间消失;设置visibility: hidden也可以隐藏这个元素,但是隐藏元素仍需占用与未隐藏时一样的空间,也就是说虽然元素不可见了,但是仍然会影响页面布局。就比如这里的下拉框都是用disply:none,导航栏有个全部商品分类是visibility:hidden;关于可视化还有个overflow:hidden使用到了。
- 关于浮动和解除浮动效果,多次使用到clear:both,float,在使用claer属性时一般是用伪元素比如::before来实现。
- 更好的理解了position这个属性,尤其是position:abosult是以最近的开启position:relavetive的父元素原点为原点。
- 也使用了transitions这个带有延迟效果的属性
- 关于居中使用到了text-align:center,margin:0 auto;和height,line-height设置大小一样的效果,
- 关于背景尺寸,使用了box-sizing:border-box
- 关于优先级,因为下拉框,可能因为优先级问题导致出不来,所有设置下拉框效果时可能需要设置z-index:;
- 了解到了transparents这种透明颜色,和rgba这种不仅包含颜色还包含透明度的属性;
- 最后是关于图标字体和网站标题的引用,首先我是在阿里矢量库里下载的文件,导入项目文件,然后引用里面的css,通常在<I>标签里应用相应的类来实现,然后网站标题icon需要下载相应的.ico的文件,然后通过<link type="icon" href=""/>.
二、代码分享

三、运行效果
一些效果具体:
网站标题
下拉二维码(有延时效果)
类似的
还有一些fixed定位和:hoverd的字体和背景背景颜色变化效果。
最后本人的一个心结:给css中的类起名时语义化非常重要。
