Looking for BootStrap alternative? Well, Bootstrap is the most popular CSS framework available, you know that right?. It is being used by many big websites like LinkedIn, Twitter, Spotify, Snapchat etc. There are many BootStrap alternatives available out there but people still use BootStrap. But there are many disadvantages of BootStrap also like, you need to override almost most of the styling according to your website, the JavaScript is tied to jQuery only, too much extra code for HTML. So that’s why I have compiled a list of most popular BootStrap alternative, which you can use for instead of bootstrap.

The components of this framework are created using HTML5 and CSS3 along with this it has numerous built-in colour schemes for uncomplicated and impressive customization.

Bootflat is fully responsive and almost all of the provided widgets are attuned with all screen sizes.


  10. Unsemantic


    This CSS framework is highly receptive and based on a fluid grid system which uses percentages instead of pixels. Percentage values are included in the layout of the grid system instead of columns. This too has pre-prepared CSS classes which makes web development an easy task for the developers. This was built using SASS with extensive focus on extensibility. This is the successor of 960.gs and includes a good amount of flexibility. Unsemantic assists the search engines to determine the significant content hence it is SEO oriented.


  11. Skeleton


    This is a very popular alternative for bootstrap. Skeleton is a small collection of stylesheets which works on 12 columns grids like flexbox in CSS. This CSS framework works amazingly for small projects. The typography in Skeleton is Raleway which is by default set at 15rem. The class names are very similar to Bootstrap. The framework is available in both .sass as well as .less versions. Skeleton uses percentage-based width for its columns.

    Although it is one of the most popular CSS frameworks and is very lightweight, it still lacks the perfection of BootStrap. Skeleton is only good for you if you need a simple and lightweight CSS framework without much configuration.


  12. Simple Grid


    This is another CSS framework based on grids. Like BootStrap, Simple Grid also divides the viewport into 12 columns. By default, it uses Lato font from Google Fonts and also font sizes are based on root rem.


  13. InK


    InK or Interface Kit is a full-fledged CSS framework that comes with almost all the functionality of BootStrap. The framework is on a bit heavy side as compared to the above-listed ones. This framework is one of my favourite on this list because of many reasons and one of them is a huge list of components.

    Interface Kit is available for download and is also available on CDN. By default, this bootstrap alternative comes with Roboto font family.


  14. TopCoat


    TopCoat is a simple and clean CSS framework which can give a tough competition to BootStrap. The framework is on a bit heavier side but also comes with good options like themes. TopCoat is developed by Adobe and is available on GitHub. The feature list of this framework includes performance testing, coding guidelines, performance measures, transition effects etc. The customization list doesn’t cover much as it is more a layer on the top of CSS.


  15. Montage JS


    This is an open-source bootstrap alternative. It helps developers to create scalable single-page web applications. The framework helps you to create reusable components. Suppose you want to use the different component on the same web page with the same base. Montage JS will help you to reuse the existing components with an additional layer of customization which will make it different from the other one. The framework also minimizes the layout to improve performance.


  16. Tailwind CSS


    This is another highly customizable bootstrap alternative which provides a lot of functionalities like BootStrap does out of the box. This framework comes in two versions, one is paid and another is free.

    Bootstrap comes with features like custom buttons, cards, alerts, progress bar etc but Tailwind doesn’t. Instead of predesigned components is uses low-level utility classes which you can use to create your own custom component. Tailwind also uses the grid structure like the other frameworks.

    The framework is a bit controversial amongst developers as some developers like to use predefined components while others don’t. So this is a framework which you may like or may not depend upon the choice.


  17. Element


    Element is a framework which is heavily dependent upon the Vue.js library. This bootstrap alternative allows you to create your own theme and comes with different colour combinations that can match your taste and requirements.

    Element is based on components which means every element on the page becomes a component. The framework is licensed under MIT which means you can use it however you want. The main disadvantage of using this framework is that you need a basic understanding of Vue.js


  18. Jeet


    Jeet is also based on the grid system in which while viewport is divided into small grids. This bootstrap alternative framework is famous for its speed as it is considered to be one f the fastest bootstrap framework. The library is built on CSS processors which means you do not need to pass the class name instead you can just pass the integer, fraction or even decimal value and it will automatically assign the processed value to the component.


  19. Metro UI


    This bootstrap alternative brings the Metro design language into web pages. If you don’t about the famous Metro design then it is the design used by the Windows Operating System.

    Metro UI also follows the grid system and is completely open-source. It comes with various components like BootStrap and has its own templating system in which you can run loops, sort, make AJAX requests etc.


  20. Mueller


    Mueller is also based on the grid system and is based on the template system. The library is mainly used for prototyping and can also handle background, padding, and typo styles etc.

    The library is based on SASS and compass. Mueller is not a completely bootstrap alternative as it lacks a lot of components and functionalities. But the advantage of using this framework is that you have full control over the column width, height and other granular settings which is not possible on other frameworks.
