重置样式
- 重置字体大小：使用语义标记不会影响样式
- 重置块边距：只有在需要时才应用间距
- 重置表格：表格数据只占用它所需的空间
- 保留了行内间距：按钮和输入保持其默认布局
- 设置边框的大小：边框和划线不会影响设置的尺寸
- 设置响应的媒体元素：以便图像和嵌入与浏览器的宽度成比例

使用REM控制布局单位
(function(doc,win){
var docEl = doc.documentElement;
var resize = "orientationchange" in window ? "orientationchange" : "resize";
var calculate = function(){
var clientWidth = docEl.clientWidth;
if(!clientWidth){
return;
}
docEl.style.fontSize = (clientWidth > 640 ? 640 :clientWidth)/320*20 + "px";
};
//不同浏览器对resize事件处理机制不同，使用定时器延迟处理resize回调函数以降低重复响应。
var timer = null;
var delay = function(){
win.clearTimeout(timer);
timer = win.setTimeout(calculate, 100);
};
//移动端无需考虑事件注册函数兼容性
if(!doc.addEventListener){
return;
}
//添加resize事件注册函数
win.addEventListener(resize, delay, false);
//DOMContentLoaded事件只在DOM文档树加载完毕后触发，因此延迟处理。
doc.addEventListener("DOMContentLoaded", calculate, false);
})(document, window);
(function(doc, win, designWidth){
var html = doc.documentElement;
var resize = "orientationchange" in window ? "orientationchange" : "resize";
var calculate = function(){
var clientWidth = html.clientWidth;
if(!clientWidth){
return;
}
//若设备宽度超过设计稿宽度则按统一值计算
html.style.fontSize = (clientWidth >= designWidth ? 100 : clientWidth/designWidth*100) + "px";
};
//不同浏览器对resize事件处理机制不同，使用定时器延迟处理resize回调函数以降低重复响应。
var timer = null;
var delay = function(){
win.clearTimeout(timer);
timer = win.setTimeout(calculate, 100);
};
//移动端无需考虑事件注册函数兼容性

背景图片缩放自适应
body{
background-color: #0b0f34;
background-image:url("/assets/stats/img/bg.png");
background-repeat: no-repeat no-repeat;
background-position: center center;
background-size: cover;
background-attachment: fixed;
}
.main{
padding:3rem 1.5rem 1.5rem 1.5rem;
background-image:url("/assets/stats/img/wrapper-bg.png");
background-repeat: no-repeat no-repeat;
background-position: center center;
background-size: 100% 100%;
}
-
background-size:cover;设置背景基于容器大小伸缩 -
background-attachment:fixed;设置当内容高度大于背景图片高度时背景图片位置先对于viewport固定
文本字体缩放自适应
