    Looking for the best CSS framework? Well, we have got you covered. Here is a list of the most popular ones with their detailed overview.

    Today, every business, even if it is brick-and-mortar, aims at having an online presence. Hence, they create responsive websites for their brands. But what are responsive websites? They are the ones whose web pages render well on devices of different screen sizes and resolutions. This is all possible with the combination of HTML and CSS .

    When it comes to CSS for creating a responsive website design, you get two options. Either you can write complete CSS code from scratch or just use one of the best CSS frameworks.

    Generally, frameworks act as the foundation or supporting structure for creating applications. They come pre-packaged with libraries or tools that take care of all the low-level functionality of an application. To put it simply, think of it as a template for your application that you can edit to add more functionality.

    If you are a master in Cascading Style Sheets, you might not need to use any CSS framework to design a web page. But if you are using one, you can design a web page like a professional.

    There are lots of properties and values along with the rules and media queries in CSS, and you have to use all these tools to make a responsive web page. Instead of writing code from scratch, we can simply use a CSS framework and its pre-defined classes and ids and save a lot of time.

    This article aims at making you aware of some of the best CSS frameworks that help you create responsive website design.

    What is a CSS Framework?

    It is a collection of pre-written CSS code that makes web designing more accessible, faster, and responsive. In other words, it comes pre-packed with CSS stylesheets that are ready to use. These stylesheets perform various web design functions, such as setting colors, fonts, navbars, layout, etc.

    Most CSS frameworks come with a grid system, which divides the complete web page into multiple grids so that the different components of the webpage can be placed in the proper areas or grids.

    Many powerful ones also use JavaScript for more functionalities and a better UI design. However, some are purely written in CSS without using JavaScript and jQuery . All of them promote the idea of not reinventing the wheel, i.e., writing code from scratch if it is already available.

    Why Should You Use it?

    Besides facilitating the development process, CSS frameworks offer the following benefits:

    • Easily and quickly implement advanced features and visual elements on a website, such as buttons, forms, breadcrumbs, navbars, etc.
    • Create cross-compatible websites, i.e., work well with different browsers and versions.
    • Ready-to-use stylesheets facilitate the web development process and eliminate the need to write code from the ground up.
    • Create easily modified, user-friendly, and visually immersive UIs.
