What are the features of css3

CSS3 is the latest version of CSS, which brings many new features and functions. The following are some of the main features of CSS3:

1. Rounded corners (border-radius)
   In CSS3, you can use the border-radius attribute to set the rounded corner effect of an element. This property can be used to set rounded corners for each of the four corners of an element, or to set rounded corners for all corners. Through this attribute, we can easily achieve effects such as rounded buttons and rounded pictures.
2. Box-shadow (box-shadow)
   The box-shadow property in CSS3 can set a box-shadow effect for an element. This property has multiple parameters that can control the color, size, offset, etc. of the shadow. Through this attribute, we can achieve more vivid element effects, such as a shadow effect when a button is pressed.
3. Text-shadow (text-shadow)
   Similar to the box shadow, the text-shadow property in CSS3 can set a shadow effect for text. This property also has multiple parameters that can set the color, size, offset, etc. of the shadow. Through this attribute, we can add more cool effects to the text, such as three-dimensional text effects, etc.
4. Media queries (media queries)
   The media query function in CSS3 can set different CSS styles for different screens according to different devices or browser widths. Through this function, we can design different page layouts and styles for three different devices: mobile phones, tablets, and computers.
5. Gradients
   The gradient function in CSS3 can set gradient color effects for text and boxes. This property comes in two types, linear gradient and radial gradient. Through this attribute, we can achieve smooth color gradient effects, such as gradient buttons, etc.
6. Animations
   The animation function in CSS3 can add dynamic effects to elements, such as gradient color, rotation, movement, etc. This attribute requires the use of the @keyframes keyword to define the animation process and termination status. Through this attribute, we can add more lively and vivid element effects to the web page.
7. Transitions
   Similar to animation, the transition function in CSS3 can add smooth transition effects to elements, such as from scratch to color change, etc. This property requires setting the transition properties, transition time, and transition easing function. Through this attribute, we can add a more natural transition effect to the element.

To summarize, CSS3 brings many new features and functions, which allow us to more easily achieve various effects and styles in web design. If you are a web designer or developer, you must understand these CSS3 features and apply them to your web design.
