Top 6 CSS Frameworks for Web Developement(2021) !

Can you imagine web development without CSS?


Though CSS worked differently in different browsers and gave us heartaches with ‘what should this

go with?’, we still cannot live without CSS and contribute to adding life to our HTML pages.

Cascading Style Sheets, known more popularly as CSS, give styles to your pages or HTML elements. You can control the layout of multiple web pages with a single style element or write custom CSS for different elements. For example, you can create an h1 element in blue color using:

h1{color: blue; text-align:center}

or set the background of your page to black:

body {background-color: black;}

All CSS components are stored in .css files. As the count of web pages increases, so do the styling elements, and your CSS file becomes large at some point. If more people work on a project, it becomes difficult to manage who changed what styles, thus creating randomness in the code.

CSS frameworks have solved a lot of randomness in developing code and got developers to sigh with relief. Different frameworks are useful for different project requirements, and each has some unique features.

Why Do We Need CSS Frameworks?

Apart from the fact that coding has become easy, here are some significant benefits of having a CSS framework:

Cross-browser functionality
Symmetrical layouts
Maintainable and device friendly styling
Good web design practices
Ensures high productivity and speed of development
