Usage of Transform in CSS
The Transform property of CSS is a very powerful tool that can perform operations such as translation, rotation, scaling and tilting of HTML elements. It can dramatically change the appearance of elements and make web pages more creative and dynamic. In this article, we will introduce the various uses of Transform in detail and provide specific code examples.
1. Translate (Translate)
Translation refers to moving an element a specified distance along the x-axis and y-axis. Its syntax is as follows:
transform: translate(x, y);
x and y are translation values ??in the horizontal and vertical directions, which can be positive numbers (right or down) or negative numbers (left or up) ). Here is an example:
.box {
width: 200px;
height: 200px;
background-color: red;
transform: translate(50px, 100px);
}This code will make a red square with a width and height of 200px move 50px to the right in the horizontal direction and 100px in the vertical direction.
2. Rotate
Rotation refers to rotating an element around its rotation center. Its syntax is as follows:
transform: rotate(angle);
angle is the angle of rotation, which can be a positive number (clockwise rotation) or a negative number (counterclockwise rotation). Here is an example:
.box {
width: 200px;
height: 200px;
background-color: blue;
transform: rotate(45deg);
}This code will rotate a blue square with a width and height of 200px 45 degrees clockwise.
3. Scale
Scale refers to adjusting the size of an element according to a specified ratio. Its syntax is as follows:
transform: scale(x, y);
x and y are the scaling ratios in the horizontal and vertical directions, which can be a number less than 1 (zoom in) or a number greater than 1 (zoom in) . Here is an example:
.box {
width: 200px;
height: 200px;
background-color: green;
transform: scale(0.5, 2);
}This code will make a green square with a width and height of 200px shrink to half its original size in the horizontal direction and double its original size in the vertical direction.
4. Skew
Skew refers to tilting elements along the x-axis and y-axis. Its syntax is as follows:
transform: skew(x-angle, y-angle);
x-angle and y-angle are the tilt angles on the x-axis and y-axis, which can be positive or negative numbers. Here is an example:
.box {
width: 200px;
height: 200px;
background-color: yellow;
transform: skew(30deg, -10deg);
}This code will make a yellow square with a width and height of 200px tilt 30 degrees clockwise on the x-axis and 10 degrees counterclockwise on the y-axis.
Summary:
Transform in CSS is a very useful property that can change the shape and position of elements through operations such as translation, rotation, scaling, and tilt. This article introduces various uses of Transform and provides specific code examples. By flexibly using the Transform attribute, we can create more creative and dynamic web page effects. I hope this article will be helpful to your study and practice!

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

Jun 12, 2025 am 10:27 AM
Vertical centering content can be implemented in CSS in a variety of ways, the most direct way is to use Flexbox. 1. Use Flexbox: By setting the container to display:flex and in conjunction with align-items:center, vertical centering of child elements can be easily achieved; 2. Combination of absolute positioning and transform: suitable for absolute positioning elements, by setting top and left to 50% and then using translate (-50%,-50%) to achieve centering; 3. CSSGrid: Through display:grid and place-items:center, horizontal and vertical centering can be achieved at the same time. If only vertical centering is required, use align
