This article introduces the style analysis of the new progress progress bar tag in html5, and explains how to change the color of the progress bar through the html5 progress tag. Next, let us read this article together

First of all, let’s get to know the introduction of the html5 progress tag:

Progress is a new element of HTML5. Indicates the definition of a progress bar, which has a wide range of uses. It can be used to display the progress of file uploads, the progress of file downloads, and can also be used as a loading status bar for loading.

Tips: Please use the tag with javaScript to display the progress of the task.

Note: The tag is not suitable for representing metrics (for example, disk space usage or query results). To represent weights and measures, use the tag instead.

html5 progress progress bar syntax:

<progress value=&#39;70&#39; max=&#39;100&#39;></progress>

Let’s prepare an example of html5 progress tag:

<html>
<head>
<meta charset="utf-8">
<title>PHP中文网</title>
<style type="text/css">
progress{
        width: 168px;
    height: 5px;
}
progress::-webkit-progress-bar
{
       background-color:#d7d7d7;
}
progress::-webkit-progress-value
{
     background-color:orange;
}
</style>
</head>
<body>
<progress value="100" max="100" class="hot">
</body>
</html>

Explain it , in the Chrome browser progress is rendered with the following structure

progress

:-webkit-progress-bar All progress

:-webkit-progress-value Completed Progress

Add styles to it through these two pseudo-elements.

But it is different in other browsers, such as IE10. These two pseudo-elements do not work. You can directly use the color style to modify the color of the completed progress, and the entire progress is background

In FireFox, the progress-bar represents the completed progress, and the background represents the entire progress. However, in Opera, this style can only be the browser default style.

Therefore, the compatibility writing method can be considered as follows:

progress
{
   color:orange; /*兼容IE10的已完成进度背景*/
   border:none;
   background:#d7d7d7;/*这个属性也可当作Chrome的已完成进度背景，只不过被下面的::progress-bar覆盖了*/      
}
progress::-webkit-progress-bar
{
   background:#d7d7d7;
}
progress::-webkit-progress-value,
progress::-moz-progress-bar
{
     background:orange;
}

The above is the code about the color css style of the progress bar, and the display effect is as follows:
