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.

You might have heard about bootstrap 5. Bootstrap is now totally jQuery free. i have tried foundation and bulma too. but eventually fall again for bootstrap, as it is most convenient and stable. i use bootstrap with less or sass.

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.

You're not correct with saying "vs Postcss". You're using Less/Sass/Stylus/... to produce "CSS" (maybe extended means it has some future features) and then in any case PostCSS will play (it is shipped with Parcel/NextJS/CRA/...)

SASS

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.

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.

Honestly - pick whatever you are the most comfortable with. You can achieve almost the same effects with different tools, so why not use something I like using?

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.

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.
