How to use translate in css3? How to use displacement translate() in css? These may be problems encountered by some novices learning CSS. Next, let’s explain how to use displacement translate() in CSS?
1: Translate() Usage
In CSS styles, many people like to use translate() to represent displacement. You can use x and y in translate() to represent the horizontal position of the element. move vertically or horizontally.
For example: 1.translateY(y): indicates that the element moves in the vertical direction, which is what we call the y-axis
2.translateX(x): indicates that the element moves horizontally Move in the direction, which is what we call the x-axis
2: translate() syntax
transform:translateX(x);或者transform:translateY(y);
In css3, the transformation method of the transform attribute belongs to transform, and transform must be added , thus indicating the deformation process. The units of the distance the element moves in the horizontal direction are expressed in px and percentage. When x appears to be a positive value, it means that the element has moved to the right in the horizontal direction. When x is a negative value, it means that the element moves to the right. Move left,
For example:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>CSS3位移translate()方法</title>
<style type="text/css">
/*设置原始元素样式*/
#origin
{
margin:100px auto;/*水平居中*/
width:200px;
height:100px;
border:1px dashed silver;
}
/*设置当前元素样式*/
#current
{
width:200px;
height:100px;
color:white;
background-color: #3EDFF4;
text-align:center;
transform:translateX(50px);
-webkit-transform:translateX(20px); /*兼容-webkit-引擎浏览器*/
-moz-transform:translateX(20px); /*兼容-moz-引擎浏览器*/
}
</style>
</head>
<body>
<div id="origin">
<div id="current"></div>
</div>
</body>
</html>The effect is as follows:
Summary: transform:translateX(50px) indicates moving in the horizontal direction 50px. At this time, if we change 50px to -50px, the element will move 50px in the opposite direction horizontally.
Usage of translate(y):
The usage of translate(y) is very similar to the usage of translate(x). x moves in the horizontal direction and y moves in the vertical direction. , when
y has a positive value, it means that the element is moving downward. If a negative value appears, it means it is moving upward, which is contrary to our normal thinking.
Mixed use of translate(x,y):
indicates that the element moves in the horizontal direction in x. It should be noted here that the y value is a parameter. If the y value is not set , may indicate that the element moves on the x-axis. In fact, simply using translate() does not make much sense. We can use it in conjunction with CSS.
