7 Best CSS Practices for Beginners

A straightforward design language created to make the process of making web pages presentable is called Cascading Style Sheets, or CSS for short.

The style and feel of a web page are handled by CSS. The color of the text, the font style, the spacing between paragraphs, the size and arrangement of columns, the background images or colours used, layout designs, variances in display for various devices and screen sizes, and a variety of other effects can all be controlled using CSS.

Today, we’ll highlight types of CSS, the main principles of CSS, Challenges that CSS practices solve or CSS Best Practices for beginners, but even seasoned professionals should brush up on the basics sometimes.

Types of CSS  

There are three different CSS types, which are listed below:

  • Inline CSS
  • Internal CSS
  • External CSS

CSS inline

Inline CSS is a style sheet that includes a CSS property in the body of an element. The style attribute of an HTML tag is used to specify this style.

Internal CSS

Internal styling or CSS may be used to style a single HTML document. The HTML file’s head section is where the CSS rule set belongs; therefore, the CSS is applied.

External CSS

External CSS comprises a separate CSS file that uses tag attributes (such as class, id, heading, etc.) only to contain style properties. CSS properties should be linked to the HTML document using the link tag written in separate files with the.css extension. This indicates that just one style can be selected for each element, and that style will be used throughout all web pages. Related Article: Useful VS Code Extensions.

The Main Principles of CSS

There are three main principles of CSS. These principles are meant to serve as a roadmap for you after you’ve chosen your strategy. These are:


The methodology or framework you select has no right or wrong solution. However, you must adhere to your guidelines no matter your decisions. Any system that is poorly built will collapse almost immediately. However, even the best strategies won’t be effective if you don’t adhere to them sincerely and regularly.

Select your methodology, choose any variations to that strategy, and then select a framework. Put your head down, get to work, and be dependable and consistent when you’re sure about your decisions.


Being concise and clear are essential components of effective CSS coding. It’s a good thing that developers are naturally lazy because there’s no need for us to write more code than is necessary. Therefore, you can’t expect your programmers to adhere to a complex CSS framework consistently and consistently.


CSS is governed by specificity and inheritance. It becomes complicated when you attempt to utilize either of them for your benefit.

Consider that every expressly styled element has a class and that no element is aware of its ancestors. You won’t have to be concerned with inheritance or specificity if you construct your system entirely flat and on a class-based foundation.

 Challenges that CSS Practices Solve

By CSS best practices, many challenges and difficulties that web developers confront may be quickly and readily overcome. The challenges faced as a web developer or designer is listed below.

Issues with code validation

The quality of your code can be evaluated by validating your HTML and CSS code. Poorly written code might make your website less functioning and negatively impact user experience. Using a validation service might reduce mistakes or misname your document.

CSS prefixes have problems

CSS prefixing, also known as vendor prefixing, is a technique for adding browser support for fresh CSS features before all browsers have fully adopted them. However, because it produces errors and defects, this system has grown to be problematic. Prefixing mistakes are simple to make, and they may be found in most CSS codes. You can utilize prefixing automation tools to resolve them.

Browser layout problems

The default style of the browser must be suitable for the design of the website. Web developers rely on layout compatibility techniques like CSS Grid and Flexbox to fix layout difficulties in browsers.

Responsive design problems

Adopting an adaptable website design approach is the best way to get visitors to your website. It guarantees that your website will be responsive across all devices. When browsing your website on various devices, there are still some potential problems. Make sure you test your equipment to identify any potential issues in order to prevent them.

7 CSS Best Practices

You must use CSS best practices to create web applications and websites with a high level of functionality and aesthetic impact. Here are CSS best practices for web developers.

1: Complete your HTML files first

Always start the web development process by using HTML to build the framework of your website. Before using CSS, you need various HTML elements on each page of your website. Once the structure is complete, you may begin styling your website with CSS selectors.

2: Implement a CSS framework

Using a CSS framework means creating websites more quickly because you don’t have to start from scratch. Access to helpful features and tools is another benefit of using a framework. Using the CSS framework decreases design errors and expedites the design process.

3: Compressing files to reduce their size

There have been times when loading the CSS codes across the browsers has been sluggish. The size of the CSS files has to be compressed. CSS compressors are being used more frequently by developers to reduce the size of the CSS file efficiently. Websites load more quickly when file sizes are reduced. It would also be beneficial if you took into account the fact that while reducing CSS file size can enhance efficiency, it also reduces CSS readability. 

4: Use a responsive design strategy

Make sure your website is adaptable and scalable before launching it. The CSS code you use should work on various mobile devices. Conducting mobile device viewing tests on your website or application to check how it appears on a mobile device is the most accessible approach.

Adopting a responsive design strategy is the best method to make your code mobile-friendly. doing this, allows you to keep your HTML code in place while modifying your CSS to fit the size and kind of t device. 

5: The Use of the CSS Reset

Resetting the CSS may help to lessen browser compatibility issues. Many frameworks have a reset option to eliminate the browser’s erratic line heights, headings, font sizes, margins etc. These elements may appear differently depending on the browser. Thanks to the reset, the layout will appear the same in all browsers. Normalize.

6: Don’t use inline styles

Although they can be helpful in some circumstances, inline styles often slow down and ineffectively create websites. After all, adding inline styles takes a lot of time and may increase the size of your site and the time it takes to load. Instead, external style sheets are employed by the majority of skilled developers since they allow for the changes to be implemented across the entire website.

7: Validate the CSS

CSS developers may become frustrated with the layout and unwilling to perform the necessary tasks. The CSS validator might be a valuable tool to highlight potential issues in this situation. Run the CSS validator or markup to examine the errors that are shown. The validator can determine whether the CSS code is properly organized and structured. It can be creative because it cuts down on time spent on manual troubleshooting.


The future of CSS and web development is bright. It’s simpler than ever to launch complex websites thanks to CSS frameworks to support our adaptive and flexible designs. Hopefully, you now have a better understanding of what CSS is. A language like CSS might be challenging to learn. It necessitates a lot of troubleshooting, time, and patience. But as soon as you start utilizing this language, you’ll see its advantages as a potent programming tool.
