When developing front-end web pages, some gradient effects are often used, which can make the front-end page more beautiful. So how are these gradient effects implemented using css code? This chapter will show you how to achieve gradient effect in css? Implementation of css background color gradient and text gradient effects (code example) , introduces css gradient style and how to implement css gradient. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.
1. css background color gradient style
##1. css linear background gradient styleSyntax:
background-image: linear-gradient(<point> || <angle>, <stop>, <stop> , <stop>)
The first parameter is the starting point or corner of the gradient. The second parameter is a color stop point (color stops). At least two colors are required (starting point and end point), and you can add any color to increase the richness of the color gradient. The color stop point can be defined as a color, or a color plus a percentage.
Code (considering browser compatibility):

You can see two The difference between the two linear gradients is that the first color value (#fd0d0d) of the three color values in background-image: linear-gradient(); becomes the angle value: 45deg.
css radial color gradient (Radial Gradients) and linear gradient (linear gradients), it does not gradient along one direction, but takes a point as the center and radiates gradients around, 360 degrees. Currently, all browsers except IE support css radial color gradient (Radial Gradients), but they also have their own different syntax
Syntax:
background-image: radial-gradient([<position> || <angle>]，[<shape> || <size>]，<stop>，<stop>，<stop>)
Code example (consider browser compatibility):
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>css背景渐变--径向渐变</title>
<style>
.demo{
width:500px ;
height:200px;
margin: 50px auto;
}
.demo *{
width:200px ;
height:200px;
margin: 50px 15px;
float: left;
}
.demo1{
background-image: -moz-radial-gradient(#ecff05, red);
background-image: -webkit-gradient(radial, center center, 0, center center, 220, from(#ecff05), to(red)); /* old */
background-image: -webkit-radial-gradient(#ecff05, red); /* new syntax */
background-image: radial-gradient(#ecff05, red);
}
.demo2{
background-image: -moz-radial-gradient(45px 45px 45deg, circle cover, #ecff05 0%, orange 100%, red 95%);
background-image: -webkit-radial-gradient(45px 45px, circle cover, #ecff05, red);
background-image: radial-gradient(45px 45px 45deg, circle cover, #ecff05 0%, orange 100%, red 95%);
}
</style>
</head>
<body>
<div class="demo">
<div class="demo1"></div>
<div class="demo2"></div>
</div>
</body>

2. CSS font text gradient styleCode example (consider browser compatibility):
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>css字体文字渐变</title>
<style>
.demo{
width:500px ;
height:200px;
margin: 50px auto;
font-size: 20px;
background-image: -webkit-gradient(linear, left 0, right 0, from(rgb(166, 4, 249)), to(rgb(251, 223, 11)));
/*必需加前缀 -webkit- 才支持这个text值 */
-webkit-background-clip: text;
/*text-fill-color会覆盖color所定义的字体颜色： */
-webkit-text-fill-color: transparent;
}
</style>
</head>
<body>
<div class="demo">css字体文字渐变,css字体文字渐变</div>
</body>
</html>Rendering:
background-image: Define the gradient color used Scope;
-webkit-background-clip: text----Use the text in the block as the cropping area to crop outwards. The background of the text is the background of the block, and the area outside the text will be cropped. ;-webkit-text-fill-color: transparent---Retrieve or set the text fill color in the object.
Since the current text-fill-color attribute seems to be supported by webkit core browsers, the two demo pages can only be used in Chrome browser or The gradient effect can only be seen in Safari browser. Solid color under Firefox browser, not to mention under IE.
