CSS3 is the most recent version of the CSS standard. It is only compatible with Internet Explorer 9 and not with previous browser versions.
The more you code, the more you will learn about CSS3, but one thing to keep in mind is that you cannot master CSS3 unless you are already familiar with CSS. CSS3 enhanced the attributes of CSS by adding additional capabilities to make them easier to use for designers.
In comparison to CSS, which does not support responsive design and is incapable of handling media queries, CSS3 supports responsive design and is capable of handling media queries. CSS3 is critical for web designers since it expands the possibilities for building a webpage. Marketers can easily increase product awareness in the market through web design.
Taking a free CSS3 tutorial can help you learn everything you need to know about the various versions of CSS.
In this blog, we will talk about the differences between CSS, CSS2, CSS3.
CSS's History
CSS was founded in 1994. CSS has evolved through time, and the World Wide Web Consortium has maintained standards with CSS1, CSS2, and CSS3.
They were stacked one on top of the other to maximise adaptability and functionality. Each had shortcomings that were rectified in the subsequent standard.
CSS has significant adaptability challenges as a result of the proliferation of web browsers throughout the years, beginning with:
· Internet Explorer
· Opera
· Firefox
· Chrome
· Edge.
CSS 1
In 1996, CSS 1 was adapted. It was more difficult to use and less adaptable to browsers such as Internet Explorer 3, Internet Explorer 4, and Netscape 4.x at the time.
CSS 1 included font properties and typeface and emphasis specifications. Text properties such as letter spacing and line spacing were supported.
Additionally, text alignment, placement, and tables were introduced. Additionally, margin, padding, border, and element placement were implemented.
CSS2
CSS2 is an enhancement to CSS1. It removed features that were not fully interoperable. Additionally, it provided browser extensions.
It introduced a number of novel features, including absolute, relative, and fixed positioning of items. It supported a variety of media formats.
Additionally, new font attributes such as shadow were included.
CSS3
CSS3 is the most modern and widely used standard. It conforms to the XHTML specification. CSS3 places a premium on modularity and concern separation.
CSS3 is supported by nearly all modern web browsers. It also includes new selectors, combinators, and pseudo-elements.
CSS3 introduces a number of new CSS attributes. It includes animation, which was not included in previous recommendations.
Numerous properties were added, including transforms, gradients, animation, and transition, to create an animation effect. Border-radius, box-shadow, flex-box, and CSS grid are all recent additions.
Internal CSS
By utilising an internal style sheet, you ensure that the style you generate is embedded directly into the HTML of that particular page, between the tags. It is used when the style should be applied to the entire HTML body.
External CSS
Using an external style sheet requires you to generate a .css file and then incorporate it into your HTML page. External CSS is typically utilised when you have a large number of HTML attributes and desire to use them as needed. There is no need to write and modify the CSS style in the HTML body repeatedly. External style sheets are strongly recommended for two reasons.
· It significantly reduces the time required for your page to load.
· It's convenient to have everything in one location.
Inline CSS
By utilising inline CSS, all styles of information will be included within HTML components. It is appropriate for a small section and when your requirements are very specific, as it affects only a single element. It is not suggested to utilise inline CSS if you are a skilled programmer for the following reasons:
· Specifying CSS for each HTML tag is time-consuming.
· The code will grow in size and complexity.
An internal style sheet is generally used by bloggers, an external style sheet is used in WordPress, and inline CSS is useful in need of quick fixes.
Any CSS3 tutorial can teach you how to use all of these style sheets and help you begin a career in CSS.

Advantages of CSS
1. Reliability
The primary advantage of CSS is that it ensures consistency of style across multiple web pages.
A single command line can handle many locations simultaneously, which is highly advantageous if adjustments need to be made. You only need to change one thing, and the rest will take care of itself. Because you do not need to alter each page individually, web designers can create and modify a website with only a few lines of code.
2. Increased website performance
Web designers only need a few lines of code for each page. Additionally, when there is less code, there are fewer lines to read, resulting in a faster page load time.
With online customers unwilling to wait for a website to load, optimising website speed is critical. CSS benefits website owners who rely on website performance to boost search engine rankings and customer base.
3. Ease of maintenance
Not only does a cascading style sheet simplify website building, but it also simplifies website maintenance.
All the codes are included on a single page, which eliminates the need to navigate across numerous pages while making changes or modifying a few lines. Furthermore, because a single line of code changes the entire website, maintenance time and effort are considerably reduced.
Disadvantages of CSS
1. Are available in a variety of levels
There are several versions of CSS, from CSS 1 to CSS 3, which has caused confusion among developers. It would have been preferable to not have to select a CSS level.
2. Fragmentation
When it comes to CSS, what works in one browser might not work in another. This is why web developers must test for compatibility by running the program in a variety of browsers prior to publishing a website.
Thus multiple testing is required.
3. Inadequate security
Due to the fact that CSS is a text-based system, it lacks the built-in security that prevents it from being overwritten. Anyone with read/write access to a website has the ability to modify the CSS file, alter the links, and cause formatting to break.
Significant Distinction CSS, CSS2, and CSS3
1. CSS was first introduced in 1996 and includes attributes for adding font properties to text, backgrounds, and other elements, such as typeface and emphasis color. CSS2 was published in 1998 with the addition of styles for different media types, allowing it to be used for building page layouts. CSS3 was released in 1999 and included presentation-style properties that enable the creation of presentations from documents.
2. Unlike CSS2, which was a single document, CSS3's specifications are divided into numerous individual modules, making it much easier to manage.
3. With CSS3, designers can now incorporate specialized fonts, such as those found in Google Fonts and Typecast. Previously, with CSS and CSS2, designers could only use "web-safe fonts" to ensure that fonts were displayed consistently on all machines.
4. While CSS and CSS2 used simple selectors,' CSS3 uses the term 'a series of simple selectors' to refer to the components.
5. CSS3 introduced some critical web design considerations, such as rounded borders, which simplify the process of rounding up borders. This proved to be a significant benefit for developers who were having difficulty with the original versions of CSS borders.
6. CSS3 enables the splitting of text parts into numerous columns, similar to how a newspaper is read. CSS2 developers encountered difficulties because the standard did not include a mechanism for automatically breaking text to fit within a box.
Conclusion
CSS is a web development tool that helps make each web page look and feel the way it does. It is proving to be able to do so much more now that it has evolved so much. CSS versions keep getting better and better over time, which means that web developers will be able to write more efficient and faster web designs.
