The main difference between CSS and CSS3 is that CSS is a simple design language that allows you to create attractive web pages, while CSS3 is the latest third version of a cascading style sheet language that has new features that allow you to work with web design much more efficiently.

A modern website consists of three different files or codes: HTML, JavaScript and CSS. HTM defines the structure of a website; JavaScript defines the behavior of a website; and CSS defines the overall look and feel of a website. The CSS specifications are supported by the W3C. On the one hand, we have the basic version, and on the other hand, we have the latest and most powerful version of CSS3. The following is a discussion of the differences between the two.

What’s the difference between CSS and CSS3?
Selectors. Selectors are at the heart of cascading style sheets, and are the templates used to select the HTML elements you want to style. CSS3 offers a whole new, robust set of tools with advanced selectors that allow you to choose more specific elements to style, eliminating the need for those arbitrary identifiers and classes that you so often include. With such a broad set of selectors, you can target almost any element on the page. CSS3 extends the basic functionality of the attribute selector by allowing you to select elements based on strings in attribute values.


CSS3 offers some exciting new ways to play with colors. Previously, colors were declared in hexadecimal format, a numbering system beginning with 00 and ending with FF. The CSS3 color specification defines an expanded list of color keywords that web browsers support. The list now includes an additional 147 color keywords and a new model called “RGBA” (added alpha channel) that allows you to define color opacity. The most significant change is that you can now declare translucent colors.

Rounding block borders. The CSS property “border-radius” defines rounded corners of any element, which makes it easy to use rounded corners in design elements. With CSS3, you can even use images for borders and create rounded corners on borders without images or additional markup. It also has additional background properties such as the ability to have multiple backgrounds and enhancements to control background image size, orientation, and cropping. The “box shadow” property allows you to add shadows to elements.

Text formatting.

CSS3 provides many text formatting properties, many of which are already present in CSS2, but with some additional features such as a new “text shadow” property. This new “text shadow” property allows you to add shadows to individual characters in text nodes. The text shadow effect makes the web page more vivid and attractive. Before CSS3, you could do the same thing by using an image or a duplicate text element and then having to place it.


Gradients are one of the most anticipated features to become native to CSS. These are incredibly powerful add-ons to CSS that allow you to set a gradient background color for an element. And you can use a simple two-color gradient, or you can make everything possible using multiple color points and different opacity levels throughout the gradient. Gradients can be linear or radial and create visual effects that are as visually rich as gradients in other techniques such as SVG.

Transitions and animations.

CSS3 has another interesting feature called “transitions” that allows you to control the speed of the animation as it transitions from one value of a CSS property to another. For example, you can animate the height of an element from zero to a hundred pixels to show the content of the element. CSS3 animations have their own specification, and they allow you to create keyframes to control the animation and properties that allow you to control the time, duration, and cyclicity of the animation.

In conclusion.

CSS3 is in every way a worthy successor and contains many interesting new features that will help in web design. It has many powerful features that make web design easier, simpler and more flexible than ever. CSS3 not only gives users lots of interesting new features to play around with, but also gives users more flexible ways to solve existing problems. CSS3 now has more than 40 modules in various stages of completion and browser support. CSS3 has an entirely new set of tools with advanced selectors that allow you to choose more specific elements to style.
