The way your website looks and feels to its audience is a huge determinant of the user experience (UX) offered on it.

Making the pages of your website more presentable comes easy with the implementation of Cascading Style Sheets (CSS) that help you decide the layout of your web pages. This language is a cornerstone technology that lets you control the look and feel of your online website, all from one place i.e the external style sheet.

In the following blog post, we will be talking about the advantages and disadvantages of CSS. However, if you are not aware of what CSS is and what functions it serves, here is a brief guide.

What is CSS (Cascading Style Sheets)?

An abbreviated form for ‘Cascading Style Sheet’, CSS is what goes into the website’s layout formatting. It is a collection of formatting rules that helps website developers control the appearance and display of the website they are working on. CSS lets them define the styling decisions such as the position of the images, the font size, the color to the background, and everything else that has an impact on how a website will display on your web browser. Besides, using the online editor you are able to organize, tidy up your style sheets and easily compress the CSS.

With CSS, the designer is able to implement functions that were earlier not defined in a page’s HTML(used for the creation of the web pages). With the new development, HTML and CSS work hand in hand to create a great website. The best thing about CSS is its capability of introducing uniform changes on all the pages of a website.

Developers work to define a style in cascading style sheet and they can use the style throughout several pages by just referencing to that particular CSS file. Hence, the amount of styling work is saved and repetition is eliminated.

CSS instructs the display of the HTML as to how the website will display at the user’s end. For the role it plays, CSS does have its own both sides of being. Let’s have a look at the advantages and disadvantages of CSS.

Advantages and Disadvantages of CSS

Before we begin, it is important to note that CSS is a functional language that enables responsive designs on a website. Its usage is what really determines the advantages and disadvantages of CSS.

Advantages of Cascading Style Sheet (CSS)

Saves Time

Let’s consider an example. You run a website that has 40 pages or more. Due to the need for some strategic changes in the content of the website, you now need to change the text size from 14pt to 12pt or vice-versa. How much time do you think will it take for manually making the size changes to all those 40 pages? A lot!

This is where CSS comes into the scenario as a savior. You can then define the changes in a single CSS file and reference all those 40 pages to that same file and your work will be done. Your entire website will start reflecting the size changes.

Help to Make Spontaneous and Consistent Changes

Considering our very own example from the first advantage above, imagine that you have to make more fluid changes to your content. Again, with a single style sheet, you will be able to ensure that the changes look uniform on all the pages and not botched up.

If it were not for CSS, you would have to take notes of changes made to one page and reference it while you make changes to another page, always going back and forth. Imagine the amount of exhaustion and brain activity that would be required to justify the consistency of these changes throughout. However, with CSS, your changes are well applied consistently.

Improves Page Loading Speed

Code density on your website contributes to its speed. The more the code, the slower the website gets. FYI, visitors are quick to abandon a website if it takes more than 2-3 seconds to load.

Just a few lines of code is all that is required to make changes to a large number of pages on the website with CSS. Since there is minimal code, the website database remains uncluttered, thus, eliminating any website loading issues. Implementing CSS along with the choice of best website builders is a great way to keep visitors hooked on to your website as they won’t have to wait up for your website to load.

Device Compatibility

CSS changes are device friendly. With people using a whole lot of different range of smart devices to access websites over the internet, there is a need for responsive web design. Bootstrap 4 templates based on CSS serve the purpose here by making your web pages more responsive so that they end up displaying in the same manner on all devices.

Ability to Re-Position

CSS lets you define changes in the position of web elements present on a page. With its implementation, developers can position HTML elements at the place they like in order to align with the aesthetic appeal of the page or other similar considerations.

Makes the Search Engine Better Crawl Your Web Pages

CSS is secretly an SEO enabler for your site. The truth is that the search engine bots yield inaccurate details when they crawl through cumbersome heaps of HTML code. However, with CSS in place, the website design attributes are defined and there is less code on the site, making the website SEO friendly.

And, if you are an expert, you can use CSS to help the search engines better assess your content for improved search engine rankings.

Disadvantages of Cascading Style Sheet (CSS)

Cross-Browser Issues

Implementing initial CSS changes on a website is easy on the developer’s end. However, after the changes have been made, you will have to confirm the compatibility if the CSS is displaying similar change effects on all the browsers. This is simply due to the fact that CSS works differently on different browsers.

Confusion Due to Its Many Levels

The programming language world in itself is crazily complicated for non-developers and beginners. To add to that,  different levels of CSS i.e. CSS; CSS 2; CSS 3 can be quite confusing for the mentioned lot.


If you have worked with CSS, you probably know that it is easily accessible because of its open text-based system. An accident or a mere act of mischief with the files can end up disrupting the display and formatting of your entire website. It would only require a read/write access to the intended website to override the changes.


Implying in the context of the advantages and disadvantages of CSS talked about above, it is fair to establish that advantages of CSS dawn over the disadvantages of CSS.

CSS empowers a web designer to make extensive changes to the web layout of all pages of a website through a single file. It lets you design a light yet responsive website which is fast to load and great at impressing the audience with its display. Hence, every website needs to have its fair share of CSS regardless of the many advantages and disadvantages of CSS.
