网页开发初体验

Html

原文：https://www.zybuluo.com/Tyhj/note/847469
一直想学一下网页的，都没机会也不知道从何下手。平时常上的网页都很好看，觉得很有意思，最近就想模仿一下 慕课网的首页，做一个像样子的网页。
其实之前也写过两次网页，都是为了交作业，虽然感觉还是挺有意思的，但是也没有深入了解，时间久了就忘的差不多了。

花了三天时间，总算是做完了，效果图(打开网页)：

我感觉还好，想不到这么快就完成了，其实很简单，就是html+javaScript+css而已，都是边做边学。

自己觉得要注意的地方：

  1. /*垂直居中*/
  2.             position: relative;
  3.             top: 50%;
  4.             transform: translateY(-50%);
  6. /*列表横排*/
  7.             display: inline;
  10. /*鼠标移动变小手*/
  11.         cursor: pointer;
  13. /*input设置无边框*/
  14.             color: grey;
  15.             border-top-width: 0px;
  16.             border-right-width: 0px;
  17.             border-bottom-width: 1.2px;
  18.             border-left-width: 0px;
  19.             border-top-style: none;
  20.             border-right-style: none;
  21.             border-bottom-style: solid;
  22.             border-left-style: none;
  23.             border-bottom-color: gainsboro;
  24.             outline: medium;
  25.             height: 30px;
  27. /*实现阴影*/
  28.             box-shadow: 0px 5px 10px gainsboro;
  30. /*全屏无边距*/
  31.         html, body {
  32.             margin: 0px;
  33.             height: 100%;
  34.             width: 100%;
  35.             font-family: "Microsoft YaHei";
  36.         }
  38.   /*设置div宽度为100%，但是最小宽度为1300px，防止小窗口下div长度仅仅为窗口的长度，导致显示背景不完整或者布局混乱*/
  39.         #container {
  40.             width:100%; min-width:1300px;
  41.             background: white;
  42.         }
  45.  /*子布局在父布局里面的对其方式*/
  46.             text-align: center;
  48. /*align 属性规定 div 元素中的内容的水平对齐方式*/
  49. <div align="center">
  51. /*vertical-align 属性设置元素的垂直对齐方式*/
  52. vertical-align:text-top;

其他的都忘了，附上源码：

  1. <!DOCTYPE html>

  13.         function inputHintOnblur() {
  14.             var hint = document.getElementById("input_search");
