Combining html and css to implement adaptive code for mobile web pages

The content of this article is about the code that combines HTML and CSS to realize mobile web page adaptation. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

First, I am working on a project recently, writing mobile web pages, mainly about adaptive issues. If you don’t use bootstrap and other front-end frameworks well, and you don’t want to waste time, it’s annoying that you can’t adapt. Here I will introduce my method to you.

is also a combination of many people’s ideas.

1. Add this line of code to the head:

<meta content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0" name="viewport">

This sentence is to automatically set the zoom. However, it cannot fully adapt to all mobile phones, and you are using a browser phone It may be normal during mode debugging, but it is actually abnormal when switching to the real mobile phone. So we still have to make changes.

2. It is recommended that you use rem instead of px when using magin, padding, font-size, and other attributes. You may be unfamiliar with rem. Here I have provided a piece of js code, which can be imported directly. , there is no need to worry about what rem is. Regarding the principle, I will write another blog to introduce it. This blog will talk about how to use it. It is the following js code, which can be put into html when writing a web page. The 640 in the code below refers to the screen width of the mobile phone. Generally speaking, the maximum width of the mobile phone screen on the market is 640px, so i=640 is used here to refer to the maximum width of the screen, the minimum is 320px, and then by citing the following js You can write your own web page. Remember that 1rem=100px in this js is actually for easy conversion. For example, font_size:14px; we can write, font_size:0.14rem.

<script>
!function(n) {
    var e = n.document,
    t = e.documentElement,
    i = 640,
    d = i / 100,
    o = "orientationchange" in n ? "orientationchange": "resize",
    a = function() {
        var n = t.clientWidth || 320;
        n > 640 && (n = 640),
        t.style.fontSize = n / d + "px"
    };
    e.addEventListener && (n.addEventListener(o, a, !1), e.addEventListener("DOMContentLoaded", a, !1))
} (window);
</script>

3. Okay, let me show you the effect of a carousel to illustrate. First, enter the code

<meta content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0" name="viewport">
