Understanding of mobile web page production (relevant meta tags)_html/css_WEB-ITnose

Recently I have been looking at JQuery Mobile, a mobile development framework. To be honest, it is really a headache~~~~ because there are many properties, methods and events~~~

The following are some understandings of mobile web pages:

1.

Add the following meta tag to the head of the mobile wap2.0 web page. The page will be displayed in the original size in the iPhone browser and scaling is not allowed.

width - The width of the viewport height - The height of the viewport
initial-scale - The initial scaling ratio
minimum-scale - The minimum ratio that the user is allowed to zoom to
maximum-scale - The maximum ratio that the user is allowed to zoom to
user-scalable - whether the user can manually zoom

2.

When the HTML page is on the mobile phone When browsing, this tag is used to specify whether to display the mobile phone number in the web page content as a dialing hyperlink.

The default on iPhone is:

If you don't want the phone To automatically display the phone number in the web page as a dial-up hyperlink, you can write like this:

3.

Note: The website enables Support for web app programs.

4.

Description:

The color of the status bar (top bar of the screen) in web app applications;

The default value is default (white), which can be set to black (black) and black -translucent (grey translucent).

Note: If the value is "black-translucent", it will occupy the px position of the page and float above the page (it will cover the 20px height of the page? The Retina screen of iphone4 and itouch4 is 40px).

! ! ! ! Other settings for the Apple web app:

Of course, additional code at both ends is required to match the icon and startup interface of the web app, as shown below:

<link rel="apple-touch-icon-precomposed" href="iphone_milanoo.png" />

Explanation: This link is Set the path of the icon file on the home screen of the web app

Use:

What needs to be noted about this path is that it is placed in the document root directory of the website but not the document root directory of the server.

The image size can be set to 57*57 (px) or Retina can be set to 114*114 (px), and the ipad size is 72*72 (px)

<link rel="<strong>apple-touch-startup-image</strong>" href="<strong>milanoo_startup.png</strong>" />

Instructions: This link is the interface when setting up the startup (picture 5), and the placement of the path is similar to the above.

Use:

What needs to be noted about this path is that it is placed under the document root directory of the website but not the document root directory of the server.

Officially stipulates that the size of the startup interface must be 320*640 (px). I originally thought that the Retina screen could support double the size, but it does not support it and the image cannot be displayed.

5. "After adding to the home screen", full screen display
The function of this meta is to delete the default Apple toolbar and menu bar. content has two values ​​"yes" and "no". When we need to display the toolbar and menu bar, there is no need to add this line of meta. The default is to display it.

//will not Recognize email
Tell the device to ignore the numbers on the page as phone numbers
Use rel="apple-touch-icon" for iOS and rel="apple-touch-icon-precomposed" for Android. In this way, when the user saves the web page as a bookmark, an application-style icon can be created on the mobile phone's HOME interface.
