Bootstrap vs Semantic UI: What are the differences?

Bootstrap and Semantic UI are both front-end CSS frameworks that provide a set of pre-designed elements and components to facilitate web development. Let's explore the key differences between them.

  1. Design Philosophy: Bootstrap focuses on providing a sleek and minimalist design, with a clean and modern aesthetic. It offers a wide range of customization options and a grid system for responsive layouts. In contrast, Semantic UI puts emphasis on natural language and intuitive class names, aiming for a more semantic and readable HTML structure. It encourages the use of descriptive class names that better reflect the intended purpose of the elements.

  2. Ease of Use: Bootstrap is known for its ease of use and extensive documentation, providing a consistent and predictable framework that is straightforward to implement. It offers pre-built components and utility classes, making it easier to quickly prototype and build responsive websites. Semantic UI, on the other hand, has a steeper learning curve due to its emphasis on semantic class names and a more extensive set of concepts. However, once understood, Semantic UI can lead to more readable and maintainable code.

  3. Customization Options: Bootstrap allows developers to easily customize the framework by using SASS variables or by overriding the default CSS classes. It provides a wide range of themes and templates that can be easily modified to fit specific design needs. Semantic UI also provides customization options but focuses more on theming and creating unique designs through a variety of built-in variables and a theming API. It offers a greater level of control over the visual styling of components.

  4. Component Availability: Bootstrap offers a comprehensive set of ready-to-use components such as navigation bars, modals, carousels, and forms. These components are well-documented and offer a wide range of customization options. Semantic UI also provides a rich set of components but focuses more on the concept of modules. Modules are self-contained UI elements that can be combined to create more complex components or layouts. It provides a unique set of modules and allows for greater flexibility in component creation.

  5. Community and Ecosystem: Bootstrap has been around for a longer time and has a larger community and ecosystem. It has a wide range of third-party integrations, plugins, and themes available, making it easier to find ready-to-use solutions for various use cases. Semantic UI has a smaller but growing community and a more limited ecosystem. However, it has a strong emphasis on community contributions and encourages developers to actively participate in expanding the framework's capabilities.

  6. Learning Curve: Due to its simplicity and extensive documentation, Bootstrap has a relatively low learning curve. It is widely adopted and has a vast amount of resources available, including tutorials, guides, and examples. Semantic UI, on the other hand, has a steeper learning curve due to its unique concepts and approach. However, it offers detailed documentation and a comprehensive set of examples to help developers grasp its concepts and best practices.

In summary, Bootstrap excels in ease of use and customization options, with a large community and extensive documentation, while Semantic UI focuses on semantic class names, modular design, and encourages a more natural language approach.

I am a bit confused when to choose Bootstrap vs Material Design or Tailwind CSS, and why? I mean, in which kind of projects we can work with bootstrap/Material/Tailwind CSS? If the design is made up on the grid, we prefer bootstrap, and if flat design, then material design. Similarly, when do we choose tailwind CSS?

Any suggestion would be appreciated?

I don't know about material design.

You would go with Bootstrap if you want to prototype / build something without bothering about the design at all and you are OK if everything looks kinda template-y, using bootstrap out of the box components.

Go with Tailwind if you need a sleek design, a user interface where building with components will be important (because tailwind strongly favors component-based UI), and you know you will need to extend the built-in classes with your own (because tailwind is very easy to extend)

I would personally recommend tailwind over bootstrap any day of the week.

Hi Ashish,

If you need minimal work to be done from your end and like most of the components / design available out of the box - go with Bootstrap. This is the oldest and has the widest adoption and a whole range of components built out by others.

If you like Material design, this is a good choice too. Please note that Bootstrap also has a Material theme, though it is not as native.

Both of these above frameworks are bulky and has more than what you may need.

If you like to build micro-components in a elegant way, TailwindCSS is the way to go.

Tailwind is great you don't have to mess with naming things and it is so much more flexible than the cookie cutter bootstrap, but I don't know about material UI. I recommend tailwind it's super simple to learn and has great code snippets.

I am planning to redesign my entire application, which is currently in Bootstrap. I heard about Tailwind CSS, and I think its really cool to work with. Is it okay if I use Bootstrap and Tailwind together? I can't remove Bootstrap altogether, as my application is using the js dependencies of Bootstrap, which I don't want to disturb.

Factually talking about systems, we gotta make two bold headlines about each one: Bootstrap has been around for a while, has a vast community and much probably will not be gone in a while. Tailwind in the other hand, is the trendy framework starting from the past year. Referring to UI, I really prefer Tailwind, however I can't ignore the fact that a lot of libraries that emerged felt short in the end after a few years (a point where Bootstrap kept his status).

You are able to use both them together but I advise you — it will be a mess. And you gotta hope that you won't have any kind of conflicts between class naming and other general styling.

My recommendation would be to use one and only one. Perhaps rebuild the UI with a specific framework in mind, otherwise you will start to workaround things of both frameworks to contradict each other - and your team (if you work with one) will hate you.

I use both of these regularly. If you're going to have to use Bootstrap due to your js dependencies, stick with Bootstrap. I actually prefer Tailwind, but trying to use both of them and make them "play nice" feels like making things more complex with no real benefit.

EDIT: Sorry for the late response, I just noticed how old this is. StackShare sent me this in an email for some reason so I assumed it was relatively fresh.

I'm building, from scratch, a webapp. It's going to be a dashboard to check on our apps in New Relic and update the Apdex from the webapp. I have just chosen Next.js as our framework because we use React already, and after going through the tutorial, I just loved the latest changes they have implemented.

But we have to decide on a CSS framework for the UI. I'm partial to Bulma because I love that it's all about CSS (and you can use SCSS from the start), that it's rather lightweight and that it doesn't come with JavaScript clutter. One of the things I hate about Bootstrap is that you depend on jQuery to use the JavaScript part. My boss loves UIkIt, but when I've used it in the past, I didn't like it.

What do you think we should use? Maybe you have another suggestion?

I have used bulma in several projects. We could not customize with the websites very well. Also when we need "quick solutions" Bulma is not suitable (I mean basic animations, to-top buttons, transparent navbar solutions etc. For these solutions, you need extra js codes).

Everybody knows about Bootstrap (heavy but popular).

Now we start a new project with UI kit, I like it. Pros: It is fast and lightweight and imho it has very good UI. Cons: Small community. Documentation.

Check this link for kick-off. https://github.com/zzseba78/Kick-Off

Maybe it is helpful.

Been checking out Bulma, myself, and really dig it. I like that it's a great base level jumping off point. You can get a layout going with it, pretty quickly, and then customize as you want. It definitely sounds like it's the one you're leaning towards but a big factor would be who will be using it most? Your boss, yourself, others? Whichever you like best, you'll prob be most productive with but if in the end your boss says it has to be UIkit, then best to be open-minded and give it another shot. Sometimes you may not jive with new tools in your stack, at first, but then they can become tools you learn to love. Best to you in your decision! Take care & keep safe.

I've moved away from the concept of UI kits. Not that many support CSS grid. A lot of the icons are easier to use in SVG. I've had success in the concept of design framework and design tokens. I build my brand identity in Figma, and extract in Diez. Then Diez integrates into React and SASS. Much easier because design is decoupled from software in a central authority, and software updates automatically from design changes.

I used UIKit and Bootstrap many times. I love Bootstrap for fast, easy layouts to web apps. Clean code, easiest and fastest way to write layouts for front end if you learned something before about Bootstrap. Now in React I use React-Boostrap too. About UIKit I can say its nice idea. It's easier than Bootstrap. This is good option for trainee developer to learn how u should create layout of your website, but for me UIKit have not enough functions. If you need to create something complicated, u have an error in your mind. You must create amazing code combinations for UIKit where in Bootstrap in the same ideas you have easy solutions.

Actually it really depends on your needs, there are 3 types of UI frameworks you can use:

  1. A complete set of UI components like: https://react-bulma.dev/en/getting-started.

    Pros:

    Having a lot of pre-built UI components saves a lot of time

    Cons:

    need to learn the react framework and the bulma styles, and it's harder to customize to your needs

  2. A pure css framework, like Bulma, where you write all the components yourself.

    Pros:

    A lot of flexibility to build the components you need

    Cons:

    You are bound to Bulma classes and markup.

    Takes more time since you need to build the components

  3. A utility class framework like: https://tailwindcss.com/.

Pros:

Most flexible, mix and match classes as you like and build your own markup

Very easy to customize to your needs

Cons:

Might take time to get used to and takes more time since you need to build the components

If you choose options one, then it's just a matter of deciding what style you like (material,ant, bulma) and go with the library that implements it If you go with pure css and build your own components, I can't recommend tailwind enough, I've been finding myself building entire pages without writing a single line of css.

And if later on, the designer wants to make a change to some color, or size, I just need to change one value in the config file, and the entire app is updated.

Tailwind CSSTailwind CSS

Hey Sai, My thoughts on UIkit - It's beautiful, fast, and it has good animation too. Why would I choose it ? Nothing other than giving the internet a new look .

My thoughts on Bootstrap - it's beautiful, if used well. It's very fast and has clean class naming convention unlike Uikit. Why I would choose it ? It's been tested and trusted, I can find a whole lot of resources and a community around it. Also with the type of project you working on I bet Bootstrap would do the job .

Now, considering Tailwind, it's seen as a classic, simple-to-set-up tool with clean utilities. I wouldn't think of tailwind the way I would to Bootstrap or UIkit. What do I mean ? Tailwind is more like a tool set to create your own design flow. Tailwind allows you to build unique design elements, offering you a level of customization that may be unmatched by the other frameworks.

My final thoughts.

If you have the time , setup and use tailwind it will give you a great chance when it comes to customization and performance.

I'm a big proponent of Tailwind and I personally use it whenever I get the chance, mostly because it's not really a UI-kit, but it sounds like in this case a UI-kit like Bootstrap with pre-defined components is more what you are looking for. Bootstrap is (relatively) extendable and overridable and makes it really simple to make a decent looking UI using a handful of pre-defined classes, whereas with Tailwind you configure the classes and create your own components. My main reason for replacing Bootstrap in my workflow is that it feels like the component creation has become so abstracted from the developer that any meaningful customization becomes a chore, resulting in many websites having the generic "Bootstrap-look". Nonetheless, it is effective for creating a pleasant and responsive UI. Though, I don't have any experience with UIkit.

Bootstrap is a great idea until your designer wants something that doesn't fit neatly into a 12 column paradigm. Then things start to get difficult. We've had to add customizations and tweaks to Bootstrap-ed HTML that by the time we were done, we would have been better off just going straight CSS. Bootstrap helps with responsiveness, but again, it's an "80/20" solution at best. And that 20 percent can be a nightmare. Plus, most clients have this odd belief that you just drop Bootstrap into an app, and abracadabra, your site is totally responsive over every type of screen and form factor in existence. This is not the case. We have had MUCH better and faster results with Tailwind CSS. Our designers are happy we're not trying to force them into a Bootstrap-friendly design, and even with responsive sites, development has been easier and faster.

I don't know about Bootstrap v5, but Bootstrap v3 and v4 was a nightmare when it comes to RTL. I switched to Vuetify in its early days when their RTL support is not very mature. But given that they care about RTL and have it in their roadmap and considerations, the change proved fruitful after their RTL support matured enough over time (and github issues).

Bootstrap is useful for rapid prototyping using an existing design system. Since the design system can be used in standard HTML + Javascript and can be imported for free into a Figma project, it lowers the complexity of our mock-up creation and frontend styling, all while promoting consistency. We did not choose Material UI, because it does not have a free design system to import into Figma.

Ant Design offers the most components with JS and CSS taken care of. They look clean, professional, and usable.

We paired this with Bulma for making the containers and structure reactive. Bulma (for react) make it easy to just add a section, container, and content and have it work on all platforms.

We also use Geist UI, though not recognized by Stack share, for its simple and modern feel. Highly recommend Geist if you want modern components for complicated UI's

I replaced Bootstrap with Material-UI during the front-end UI development, because Material-UI adopts a component-based importing style, making it suit well in a "React programming style". This makes me comfortable when programming because I can treat importing UI components as other React components I define.

I do prefer to write things from scratch however when it came to wanting to jump-start the frontend, I found that it was taking me a lot longer hence why needing to use something very fast.

Bootstrap was the boom when it came out, I didn't like it, to be honest, set in its way and a pain to over-ride and in addition, you can tell from a distance if you're using boostrap and as everything looks the same.

I came across Tailwind CSS as I wanted more dynamic features, you could say, I've been now doing it for a few days and I love it a lot. I've been practising with the full stack part installed but I an't we wait until I do a new project, and I'll e able to select exactly what I want. Much faster.

Fonts and typography are fun. Material Design is a framework (developed by Google) that basically geeks out on how to assemble your typographical elements together into a design language. If you're into fonts and typography, it's fantastic. It provides a theming engine, reusable components, and can pull different user interfaces together under a common design paradigm. I'd highly recommend looking into Borries Schwesinger's book "The Form Book" if you're going to be working with Material UI or are otherwise new to component design.
