如何选择合适的CSS框架

The first step you need to take is to make sure you decide upon a framework that has an established and accurate representation of detailed documentation. This is vital to the steps you’ll take in implementing and utilizing your framework the way it was intended.
首先要做的是确保你要使用的框架有确定、能够精确表现详细文档的形式。这一步至关重要，将决定你能否运用框架来达到它的设计初衷。
Next, you should analyze what problems the specified frameworks of your choice will solve. As you come across frameworks that you believe might “fit the bill” for the project(s) at hand, then it would be wise to compare each of them and elaborate on which framework addresses which concerns and satisfies your needs.
接下来，你应当分析应用某个框架可能会遇到的问题。当你手边拿到你认为可能适合你的项目的框架时，比较聪明的做法是把这些框架做一下对比，详细比较各个框架主要涉及的方面，哪个更适合你。
CSS Frameworks allow you to rapidly improve and speed up your development time when used correctly, and provide a powerful way to style our websites and applications with flexibility and effectiveness.
正确地运用CSS框架，可以迅速提高我们的开发速度，并为整个站点和应用的样式化提供一种强大、高效的而且富有弹性的工具。
Also, don’t hesitate to ask other developers and colleagues which framework has worked best for them and why? This will help you gain valuable insight based on the experience of others, something that can’t be bought. Another point I would like to make is the role your chosen framework’s community plays. How big is it? Are the members helpful? Does it provide invaluable resources? Every one of these questions help you determine if your framework’s community is going to be of use. The logical point of view is, the larger and more involved the community is, the better your chances are at finding the right type of help when you need it.
还有，不要犹豫去问一下其他的开发人员或者同事哪些框架他们用得最好，为什么？这将使你获得其他经验丰富人员的一些有价值的想法，这是无法用金钱买来的。另一点是你所选框架的社区所扮演的角色。它有多大？这些成员有用吗？它提供毫无用处的资源吗？每一个问题都会帮助你决定能否用的上所选框架的开发社区。从逻辑上说，社区规模越大、用户数量越多，你获得所需帮助的机会就越多。
