選擇CSS框架還是原生CSS取決於項(xiàng)目需求和團(tuán)隊(duì)熟練度。使用框架如Bootstrap或Tailwind能通過(guò)預(yù)製組件加快開(kāi)發(fā)速度，尤其適合原型設(shè)計(jì)或時(shí)間緊迫的項(xiàng)目，但需學(xué)習(xí)命名規(guī)範(fàn)和工具模式；而原生CSS無(wú)需額外語(yǔ)法，適合小型項(xiàng)目或需要完全控制的情況?？蚣芸赡軐?dǎo)致代碼冗餘，需手動(dòng)優(yōu)化以避免性能問(wèn)題，而原生CSS雖更靈活但開(kāi)發(fā)速度較慢且易不一致。在團(tuán)隊(duì)協(xié)作中，框架有助於統(tǒng)一風(fēng)格並簡(jiǎn)化交接，但過(guò)度自定義可能引發(fā)混亂，原生CSS則因結(jié)構(gòu)簡(jiǎn)單更易調(diào)試。因此，兩者各有優(yōu)劣，應(yīng)根據(jù)開(kāi)發(fā)效率、定制化、性能和團(tuán)隊(duì)流程進(jìn)行權(quán)衡。

Using CSS frameworks definitely has its advantages, but sticking to vanilla CSS isn't without merit either. The best choice really depends on your project's needs and your team's familiarity with tools.

Faster Development vs. Learning Curve

One big plus of using a CSS framework like Bootstrap or Tailwind is speed. You can get a site up and running fast with pre-built components — buttons, grids, navbars — all styled and responsive right out of the box. This is especially helpful for prototyping or projects with tight deadlines.

On the flip side, if you're not already familiar with a framework, there is a learning curve. You'll need to learn the class naming conventions, utility patterns (especially in utility-first frameworks like Tailwind), and maybe even how to customize defaults. With vanilla CSS, what you write is what you get — no special syntax or setup needed. If you're just building something small or want full control, plain CSS might feel more straightforward.

• Frameworks save time with ready-to-use components
• Vanilla CSS gives more creative freedom upfront
• Framework knowledge doesn't always transfer between them

Customization and Bloat

A common complaint about CSS frameworks is that they can lead to bloated code if not optimized. Sure, you get a ton of styles by default, but chances are you won't use everything. That unused CSS adds extra weight to your site unless you take steps like purging unused classes or customizing the build process.

Vanilla CSS avoids this issue altogether — you only write what you need. But then again, writing everything from scratch takes longer and increases the chance of inconsistency across your UI.

• Unused CSS in frameworks can slow things down
• Manual optimization helps, but adds setup work
• Writing custom CSS means slower start but leaner output

Maintainability and Team Collaboration

When working in teams, especially ones where not everyone is equally experienced, CSS frameworks can actually help maintain consistency. Everyone uses the same utility classes or component styles, so there's less guesswork involved. It also makes it easier to hand off work or onboard new developers who already know the framework.

But if you're not careful, even framework-based code can become messy over time — especially when people start adding custom overrides or mixing in their own styles inconsistently. Vanilla CSS can suffer from the same issues too, but with fewer abstractions, sometimes it's easier to track down what's causing layout problems or style conflicts.

• Frameworks promote consistent styling across a team
• Too many overrides can defeat the purpose of using a framework
• Pure CSS may be easier to debug due to fewer layers

All in all, whether to go with a CSS framework or stick to vanilla CSS comes down to your priorities: development speed, customization, performance, and team workflow. Neither approach is inherently better — just better suited for different situations.
