HTML5 Boilerplate is the professional badass's base HTML/CSS/JS template for a fast, robust and future-proof site.
After more than three years in iterative development, you get the best of the best practices baked in: cross-browser normalization, performance optimizations, even optional features like cross-domain Ajax and Flash. A starter apache .htaccess config file hooks you the eff up with caching rules and preps your site to serve HTML5 video, use @font-face, and get your gzip zipple on.
Boilerplate is not a framework, nor does it prescribe any philosophy of development, it's just got some tricks to get your project off the ground quickly and right-footed.

H5BP is a year old! We launched on August 10th, 2010 and now we've got a plethora of new, exciting changes that comprise our 2.0 release. We've also added Mathias Bynens and Nicolas Gallagher, two very talented frontend researchers and developers, to the core development team. The highlights of 2.0 are below, followed by a more comprehensive changelog.
We are now using normalize.css developed by Nicolas Gallagher along with Jonathan Neal instead of the traditional CSS Reset stylesheet.
normalize.css retains useful browser defaults and includes several common fixes to improve cross-browser (desktop and mobile) styling consistency.
Lots of research has gone into normalize, verifying what are the default user agent styles provided by each browser. We can very specifically change only the ones we need to instead of the bulldozer approach.
Why this is great news:
em, i { font-style: italic; }If 15 seconds was too long to wait before, you'll be happy with the changes. Via a new "intermediate" folder, we cut down build time by 80% or more.
If you use @imports in your CSS to author in multiple files, the build script will inline all these together. This way, you have a maintainable authoring experience, and still a highly performant production version.
Making an app that works offline is a badge of honor. Now with a flick of a config switch, the H5BP build script can autogenerate your cache manifest file with all the right info and wire it up. It'll also keep the manifest revved as you deploy new changes.
2.0 also gets a lot of major updates Here are all 299 commits since last release, brought to you by over 49 contributors.
Should you upgrade existing sites? Short answer: nah, you're good. (Though dropping in the new build script and .htaccess would be cool)
X-UA-Compatible HTTP header instead of leaving it in the HTML, to avoid edge case issues.
</script>.
Modernizr.load() for byte brevity and optimal speed
img { max-width: 100%; } to print styles to prevent images from getting cut off.
::selection. It is now #fe57a1, which is … vertical-align: middle to fix borders on image containers.
{cursor:pointer} to <label> element.
outline:0 for accessible focus treatment. Avoids Opera bug when combined with transitions. Also saves bytes.
{overflow:auto} for <button> and <input> in <table> in IE6/7. Avoids numerous layout and whitespace issues that result from setting {overflow:visible} to fix the odd inner spacing of those form elements.
{resize: vertical} to <textarea>. Only allow vertical resizing
Added a files.bypass property which when set, will not compress the listed JavaScript files, but just silently passes it on to the publish folder without any change.
Added a images.bypass with a list of image files or folders within the img directory that you do not want to be optimized.
@defer attribute Files are not deleted at the beginning of every build, and files that have already been processed will not be reprocessed unless the source has changed. A new "intermediate" folder is used for this.
Versioned files are referenced by a SHA-1 hash of the content rather than a build number. This means that changing your HTML and rebuilding will not cause your users to redownload the same CSS and JavaScript, and a reverted change may cause users to use a copy that was previously downloaded. It may be better to use only part of the hash so the HTTP request is shorter.
mod_filter.
Header unset ETag In some servers setting FileETag None alone, is not enough. Removing header and setting it to None fixes the issue.
Options +FollowSymlinks when RewriteEngine is used. Fixes #489.
The commit messages on these commits are particularly fun and worth a read if you're into frontend research
