HTML5 Boilerplate, HTML5 Reset CSS validation

阅读更多关于 HTML5 Boilerplate, HTML5 Reset CSS validation

I'm in the process of selecting an HTML5 template for my web projects. I've been using HTML5 Initiliazr which uses Boilerplate for the last few months but decide to reevaluate the two templates, since I don't like the issues with HTML5 Boilerplate's CSS not being valid against W3 CSS validator (CSS3). Now my question is, given the fact that both CSS resets also take into account vendor quirknesses, will those resets ever be completely valid or is it impossible to assume such a thing?

How can I use CSS3 ::selection without changing the default color and background color?

阅读更多关于 How can I use CSS3 ::selection without changing the default color and background color?

The following lines are included in the HTML5 Boilerplate template by default: ::-moz-selection{background:#fe57a1;color:#fff;text-shadow:none;} ::selection{background:#fe57a1;color:#fff;text-shadow:none;} However, I want to keep the selection color as the OS default (blue in Windows, I think it's brownish orange in Ubuntu).

阅读更多关于 How to use the .clearfix class?

I think I'm misunderstanding the concept of the .clearfix class. Maybe somebody can help me out. I'm looking for a way to use float and clear without messing up my markup. So I thought, that's where .clearfix can be used for. Inside of an empty H5BP-project, my markup looks like: <div></div> <div></div> <div class="clearfix"></div> <div></div> <div></div> <div class="clearfix"></div> <div></div> <div></div> <div class="clearfix"></div> Below the result. I was expecting a tic tac toe-field, though. Can somebody tell me: How I can achieve my goal and What the .clearfix class really can be used
