CSS vs JavaScript

Web development is divided into two ends front-end and backend, front-end deal with the interactive nature of webpages and backend deal with the logic & database. HTML, JavaScript, and CSS are the 3 major tools we used to build the front end of any web page. All these 3 tools play a major role in web development, if we highlight JavaScript here, not only in front end JS has some Frameworks which also used in backend development. We cannot imagine any web page without these three front-end tools, here in this article have provided a head to head comparison between CSS and JavaScript because in many cases both of these tools cross over each other and both can be embedded in an HTML page with specific tags.

Difference between CSS vs JavaScript

What is CSS?

CSS stands for Cascading Style Sheets which is used to style the web pages which includes design, layout, and variations in the display. It was developed by W3C World Wide Web Consortium so it could solve the problem with the HTML individual line styling.

Vamware

Everything that we see on a webpage with color and layout is because of CSS and its Framework. Now more than using a direct CSS code we use its frameworks because they can adjust the web-page layout and design according to the devise size.

Benefits of Using CSS

1. Separate File

Before the introduction of CSS, we have to visit every tag if we want to style a particular element, but with CSS we have a new markup language that is capable of styling the complete HTML file. With CSS we can create different files that do not need to be a direct part of HTML structure but can be imported in it.

2. Fast load pages

The CSS file can be cached into the browser memory after one request so the browser does not need to download the CSS file of a particular page if we visit it again.

3. Presentation

As we all know that CSS is used to color the static structure of HTML, CSS can even change the format of text and provide control over the HTML structure.

4. Search Engine Optimization

With CSS we simply reduce the extra code which we had to be written if CSS was not there, this also helps search engines to estimate the real density of the page and it improves the ranking index of the website.

What is JavaScript?

JavaScript is a high-level programming language that is used as a scripting language for both the client-side and server-side. Like other languages, JavaScript does not need any compiler, interpreter or assembler to run its files, it can simply run on the web browser.

Often people have the confusion that JavaScript is related to Java because of the initials of both the languages but both are different programming languages.

Features of JavaScript

  • JavaScript is an Object-Oriented Programming language
  • It can be used for both server-side as well as client-side scripting.
  • It provides action on a static HTML page.
  • Most of its syntax is similar to C programming language.
  • It is an Interpreted programming language.
  • It executes at the client side which makes it faster as compared to other programming languages.

CSS vs JavaScript: Head to Head Comparison

Below the given table, you will get head to head chart between CSS and Javascript:

CSS JavaScript

Definition

CSS stands for Cascading Style Sheet, which is used to style the HTML page. JavaScript is a programming language that can enhance HTML pages by adding some dynamic action to its static nature.

Language

CSS is a markup language JavaScript is a high-level, object-oriented programming language.

Developed by

W3C (World Wide Web Consortium) Brendan Eich

Client-Side and Server-side

CSS code execute at the Client-side, on the browser of the user JavaScript Code can be executed either at the client or server-side.

Complicated Language

CSS is easy to understand because it is not a programming language and does not have a vast area to cover various fields. As compared to the other two front end languages HTML and CSS, JavaScript is more complicated it consists mostly all the syntax of high-level programming languages.

File Extension

CSS use the file extension .css JavaScript use the file extension .js or .jms

Errors

CSS code does not throw any error JavaScript code throw errors

Resilience

As CSS code does not throw any error so even a broken code does not affect the complete web page. If there is an error in the JavaScript code, then it could have some effect on the web page.

Browser support:

Ever browser give support to execute CSS file Even every major browser gives support for JS, but there are some browsers that do not support some of the JavaScript libraries.

HTML tags:

<style> …. </style> <script> ……</script>

Application

CSS used to design, the HTML page by adding colour, layout, font style, etc. JavaScript cover more aspect than CSS, JS can be used for Security, Games, Special Effects, form handling, etc.

Some Major difference between CSS and JavaScript:

  • CSS is just used to organize the HTML pages and it cannot work alone, on the other hand, JavaScript is used to put action in the HTML pages and it can be executed alone at the browser console.
  • All the major browsers give a console on which we can execute JavaScript code.
  • CSS cannot alter any element of the HTML page but JavaScript can do this and more.
  • JavaScript cover more market as compare to CSS
  • JavaScript also stands at the top of some Index as the most popular programming languages.

Conclusion

Both CSS and JavaScript are the major tools for front end development and even back-end developers cannot ignore these tools. The comparison is just to tell the major difference between these two tools and it does not signify which is more important or which is less. We require both the languages if we want to be a web developer. It’s just that CSS is more underrated as compared to JavaScript but both the languages have their significance and we do not develop any web page without these two tools.
