比方说，如果要调试一个只有遇到包含行内图像的段落时才会出现问题的样式表。
For instance, suppose you're debugging a stylesheet that seems to have trouble when a paragraph contains an inline image.
样式表提供了，包括指定一个元素是作为块级别还是行内来展现在内的，控制元素绘制的方法。
Style sheets provide the means to specify the rendering of arbitrary elements, including whether an element is rendered as block or inline.
样式表并行加载，但是如果您有一个行内脚本跟随着样式表，并行下载规则被破坏。
Stylesheets load in parallel, but if you have a stylesheet followed by an inline script, parallel downloads are broken.
