• HTML5和CSS3扁平化风格博客(基础篇)

    多学一点总是好的~

    自始至终都觉得的css和html效果比较美观，于是在看慕课网教程时，自己也跟着敲了深爱着的前端代码

    u41234644404161681249fm26gp0_thumb4

    这部分分为两部分：①基础篇：http://www.imooc.com/learn/445；

                                    ②进阶篇：http://www.imooc.com/learn/598；

    这里只对基础篇进行记录，下篇则为进阶篇介绍。

    学到的something：

    1、CSS的常规布局方法；

    2、CSS扁平化风格布局方法 ；

    3、网页布局特殊情况处理方式 ；

    4、HTML5相关标签和CSS3效果。

    项目开始：

    拿到一个项目，先不要着急动手写代码，而是思考——这是前辈以及自己在工作后，深觉得颇为正确的道理。

    1.模块分析：先思考，再动手；

    2.重置样式及文件结构（http://cssreset.com/或者normalize.css，但是建议后者，因为前者会将所有标签，包括H1在内的元素样式全部去掉，这点不太合适，故选normalize.css。）

    3.宏观布局：

    先看最终效果吧：

    Title

    ①布局：

    23-1

    ②直接上代码：

    index.html:

    <!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <link rel="stylesheet" href="css/reset.css">
    <link rel="stylesheet" href="css/main.css">
    <style>
        /*css样式重置*/

    </style>
</head>

    兴趣真的是位好老师~

    其实css以及html方面的知识比较简单，只是过程比较“曲折”，如果有足够的兴趣，花点时间也是可以达到满意的效果的。
