1、環境搭建

基於node.js的http-server伺服器搭建

https://www.npmjs.com/package/http-server

cnpm install http-server -g

 

2、首頁實現

創建一個目錄,叫webapp,在裡面創建一個index.html

打開cmd,進入webapp目錄,輸入以下代碼:

http-server

 

 

3、在瀏覽器輸入網址:http://127.0.0.1:8080/

成功訪問到index.html

 

打開sublime-首選項-插件設置-cssrem-settings-user

37.5是iphone6設備的通用設置

{
    "px_to_rem": 37.5, //px轉rem的單位比例,預設為40
    "max_rem_fraction_length": 6, //px轉rem的小數部分的最大長度。預設為6。
    "available_file_types": [".css", ".less", ".sass",".html"]
    //啟用此插件的文件類型。預設為:[".css", ".less", ".sass"]
}

 

4、移動端滾動載入

 

 

 

首頁效果圖:

 

首先是目錄結構

 

 index.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>index</title>
    <meta name="viewport" content="width=device-width,initial-scale=1.0,maximum-scale=1.0,minimum-scale=1.0,user-scalable=no">
    <script>
        (function(){
            //這段代碼放在所有的樣式文件之前,設置html根元素的fontSize
            var docEl=document.documentElement;

            function setRem(){
                // 這個10不是固定的,只是計算出來的rem要和cssrem插件setting中設置的37.5保持一致
                // iphone6設備寬度是375,因此基準值剛好是10
                var rem=docEl.clientWidth/10;//獲取基準值
                docEl.style.fontSize=rem+"px";//動態設置html根元素的fontSize
            }

            setRem();

            window.addEventListener("resize",setRem);

            //用戶每次瀏覽頁面的時候, 就會觸發pagesshow方法(有相容性問題)
            window.addEventListener("pageshow",function(e){
                // 使用e.presisted就是判斷當前頁面是不是在緩存中載入
                // 如果緩存中載入(就是為true的時候),重新設置rem
                if(e.persisted){
                    setRem();
                }
            });
        })();
