Xiaomi Mall Responsive Learning_html/css_WEB-ITnose

What I have always longed for is Taobao’s mobile webpage, which is truly responsive through rem, but I always feel that it is quite different from the original approach on the PC. Maybe I can’t understand it. Over the weekend, I accidentally discovered that Xiaomi’s mobile webpage is also written in em mode. Looking at the source code, I found that this is the responsive wap webpage I am pursuing. Record the learning~

Basic settings

1. a tag to click on the background blue-webkit-tap- highlight-color: rgba(0,0,0,0);
   
2. Disable the text size adjustment function of Webkit kernel browser-webkit-text-size-adjust: none;
   
3. Allow long words to wrap to the next line word-wrap:break-word;

Element unit (em)

1. Includes: padding, margin, width, height, font-size, line-height, etc.
   

2. Set the base font size through the global body

   body {    font-size: 20px;}@media only screen and (max-width: 710px) and (min-width: 640px)body {    font-size: 17.77778px;}

2. Add iconfont element

   .page-index .nav-index li a .icon:before {    font-size: 4em;    color: #5c6066;    line-height: 1.375em;}

   .icon-huafeichongzhi:before {    content: "\e608";}

3. Other settings

   .page-index .nav-index li a .icon {    display: block;    margin: 0 auto .5em;    width: 5em;    height: 5em;    -webkit-background-size: 5em 5em;    -moz-background-size: 5em 5em;    -ms-background-size: 5em 5em;    -o-background-size: 5em 5em;    background-size: 5em 5em;}

   Copy after login

Layout

1. Use display: table;, display: table-row;, display: table-cell;, border-collapse: collapse; or display: box;, box-flex: 1; instead of float:left layout
   
2. Use pseudo-classes such as: first-child for difference processing
   

3. The image is adaptive based on the em width and height of the parent

   .imgurl img {    width: 100%;}li, img, label, input {    vertical-align: middle;}

   Copy after login
4. The background image size is set by background-size: 3.85em 2.7em;
   

5. Vertically centered content and horizontally centered content

   div#DemoArea {    display: box;    box-align: start;    -moz-box-align: start;    -webkit-box-align: start;    box-align: start;}

   Copy after login

   div#DemoArea {    display: box;    box-align: start;    -moz-box-pack:center;    -webkit-box-pack:center;    box-pack:center;}

   Copy after login

Summary and reflection

1. Many new CSS3 technologies have been applied which are refreshing
   
2. Is it better to use em as a unit or rem?
