How to remove web page style in uniapp

Now more and more websites have their own applications on the mobile terminal, and some new mobile application development frameworks are slowly coming into the public eye. UniApp is one of such popular mobile application development frameworks. It is completely developed based on Vue.js and WeChat applet component library and can run on multiple platforms at the same time. However, in actual development, UniApp's default web page style may make developers dissatisfied. This article will explain how to remove UniApp's default web page style.

Step 1: Clear UniApp default CSS styles

UniApp’s default CSS styles are in its base style sheet file. We can override them by introducing a custom CSS file. part style. The specific operations are as follows:

1. Create a new file named reset.css in the static directory of the project.
2. Write the following content in this file:

html, body, div, span, applet, object, iframe,h1, h2, h3, h4, h5, h6, p, blockquote, pre,a, abbr, acronym, address, big, cite, code,del, dfn, em, font, img, ins, kbd, q, s, samp,small, strike, strong, sub, sup, tt, var,b, u, i, center,dl, dt, dd, ol, ul, li,fieldset, form, label, legend,table, caption, tbody, tfoot, thead, tr, th, td,article, aside, canvas, details, embed,figure, figcaption, footer, header, hgroup,menu, nav, output, ruby, section, summary,time, mark, audio, video{
    margin: 0;
    padding: 0;
    border: 0;
    font-size: 100%;
    font: inherit;
    vertical-align: baseline;
}
/*自定义的其他样式*/

This code clears UniApp’s default CSS style (including margin, padding, border and other attributes), which is equivalent to building your own style from the bottom. We can also add other customized CSS styles below this code to further beautify the web page.

3. Reference the CSS file in the App.vue component. Add the following code in the template tag:

<style lang="scss" rel="stylesheet">
  @import "../static/reset.css";
</style>

This is to clear the UniApp default CSS style by referencing the external CSS file in the App.vue component. Here we use the import method to avoid repeatedly adding style files to the HTML file.

Step 2: reset global CSS styles

After clearing the UniApp default CSS styles, we need to add some reset global CSS styles, so as to avoid some troubles in later development.

1. Create a new file named common.scss in the static directory of the project.
2. Write the following content in this file:

html, body {
    height: 100%;
    min-height: 100%;
}

body {
    color: #333;
    font-size: 15px;
    font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;
    background-color: #fff;
}

input[type="text"], input[type="number"], input[type="password"] {
    -webkit-appearance: none;
    -webkit-border-radius: 0;
}
input[type="submit"], input[type="button"], button {
    border: none;
    outline: none;
    background-color: tranparent;
    cursor: pointer;
    -webkit-appearance: none;
    -webkit-tap-highlight-color: rgba(0, 0, 0, 0);
}
/*自定义的其他样式*/

This CSS style can solve some style inconsistency problems between different platforms. For example, in iOS and Android platforms, the rounded corners of the input boxes are different. Using this code can maintain the consistency of the input boxes on different platforms. At the same time, this code also targets some commonly used UI components, such as buttons. It can solve some inconsistencies in styles on various platforms.

3. Reference the CSS file in the App.vue component. As before, add the following code to the template tag:

<style lang="scss" rel="stylesheet">
  @import "../static/common.scss";
</style>

Among them, we cleared the default styles of all elements and customized the styles from the bottom; and reset the global CSS styles to solve some style incompatibility issues between different platforms.
