我是一个普通的H5开发者，我们花了10来个月做了一款微信应用，
但是因为最新版本的微信，选择使用了还没成熟的X5浏览器，
导致我们的应用在安卓版上完全无法使用 REST H5特效。
我相信这个世界上还有很多和我一样，因为这个问题头痛的开发猿。
所以希望能通过这个请愿书，感动TX的领导们，你们向他们学习：https://github.com/crosswalk-project/crosswalk
希望你们不要让我们开发者失望，X5真的是没法用，而且也没法改成能用，很多项目真的等不了。

如果你是开发猿请加颗星，希望能通过群众的响应改善大家的开发环境。

# this can be useful when developing against a custom DNS server, or 
# for example, if you made a change to the DNS settings of a domain, and you 
# know the authoritative nameserver IP address for a domain, you could use this 
# to bypass the intermediate DNS cache, and apply an HTTP request using the new 
# DNS settings supplied by your specified (authoritative) nameserver

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

EDIT from 2019: Hi folks. I wrote this gist for myself and some friends, and it seems like it's gotten posted somewhere that's generated some (ahem, heated) discussion. The whitespace was correct when it was posted, and since then GitHub changed how it formats <pre> tags. Look at the raw text if you care about this. I'm sure someone could tell me how to fix it, but (thank you @anzdaddy for suggesting a formatting workaround) honestly this is a random throwaway gist from 2015, and someone more knowledgable about this comparison should just write a proper blog post about it. If you comment here I'll hopefully see it and stick a link to it up here. Cheers. @oconnor663

Here's the canonical TOML example from the TOML README, and a YAML version of the same.
