What's the Difference?

CSS3 and HTML5 are both essential components of web development, but they serve different purposes. HTML5 is the markup language used to structure and present content on the web, while CSS3 is the style sheet language used to control the layout and design of a website. HTML5 introduces new elements and attributes that make it easier to create dynamic and interactive web pages, while CSS3 offers advanced styling options such as animations, gradients, and transitions. Together, these technologies work hand in hand to create visually appealing and functional websites.

CSS3 Attributes

CSS3, the latest version of Cascading Style Sheets, brings a plethora of new features and enhancements to the table. One of the most notable attributes of CSS3 is its ability to create animations and transitions without the need for JavaScript. This allows developers to add dynamic effects to their websites with ease. Additionally, CSS3 introduces new selectors such as nth-child and nth-of-type, which provide more flexibility when styling elements on a page.

CSS3 also includes new properties like border-radius and box-shadow, which make it easier to create visually appealing designs without the need for images.

With flexbox, developers can easily align and distribute elements within a container, making it easier to create responsive and flexible designs. CSS3 also includes support for variables, which allow developers to define reusable values that can be used throughout a stylesheet.

In addition to these attributes, CSS3 also includes features like text-shadow, gradients, and transformations, which give developers more control over the appearance of text and elements on a page. Overall, CSS3 offers a wide range of attributes that make it a powerful tool for styling websites and creating engaging user experiences.
