aa983b9eb8086376f1f6481364a02e5a
标签规定用于表单的密钥对生成器字段。当提交表单时,私钥存储在本地,公钥发送到服务器。是HTML5 标签。
Q2:71af07a0e88a1ac1ff73f855702ac153

71af07a0e88a1ac1ff73f855702ac153

<bdo dir="rtl">Here is some text</bdo>
Q3:下列HTML代码是否正确?
<figure> <img src="myimage.jpg" alt="My image"> <figcaption> <p>This is my self portrait.</p> </figcaption> </figure>
A:正确
24203f2f45e6606542ba09fd2181843a
标签规定独立的流内容(图像、图表、照片、代码等等)。figure 元素的内容应该与主内容相关,但如果被删除,则不应对文档流产生影响。使用614eb9dc63b3fb809437a716aa228d24
元素为figure添加标题(caption)。
Q4:哪种情况下应该使用small标签?当你想在h1 标题后创建副标题?还是当在footer里面增加版权信息?
A:small标签一般使用场景是在版权信息和法律文本里使用,也可以在标题里使用标注附加信息(bootstrap中可见),但不可以用来创建副标题。
The HTML Small Element (
d015d241ae6d34c34210679b5204fe85
) makes the text font size one size smaller (for example, from large to medium, or from small to x-small) down to the browser's minimum font size. In HTML5, this element is repurposed to represent side-comments and small print, including copyright and legal text, independent of its styled presentation.
Q5:在一个结构良好的web网页里,多个h1标签会不利于SEO吗?
A:不影响。
According to Matt Cutts (lead of Google's webspam team and the de facto expert on these things), using multiple 4a249f0d628e2318394fd9b75b4636b1 tags is fine, as long as you're not abusing it (like sticking your whole page in an 4a249f0d628e2318394fd9b75b4636b1 and using CSS to style it back to normal size). That would likely have no effect, and might trigger a penalty, as it looks spammy.
If you have multiple headings and it would be natural to use multiple 4a249f0d628e2318394fd9b75b4636b1's, then go for it.

Q6:如果你有一个搜索结果页面,你想高亮搜索的关键词。什么HTML 标签可以使用?
A:f920514e6447cf1d171079d1371f007f
标签表现高亮文本。
The HTML
f920514e6447cf1d171079d1371f007f
Element represents highlighted text, i.e., a run of text marked for reference purpose, due to its relevance in a particular context. For example it can be used in a page showing search results to highlight every instance of the searched for word.
Q7:下列代码中scope 属性是做什么的?
<article> <h1>Hello World</h1> <style scoped> p { color: #FF0; } </style> <p>This is my text</p> </article> <article> <h1>This is awesome</h1> <p>I am some other text</p> </article>
A:scoped 属性是一个布尔属性。如果使用该属性,则样式仅仅应用到 style 元素的父元素及其子元素。
Q8:HTML5 支持块级超链接吗?例如:
<article> <a href="#"> <h1>Hello</h1> <p>I am some text</p> </a> </article>

HTML5中3499910bf9dac5ae3c52d5ede7383485 元素表现为一个超链接,支持任何行内元素和块级元素。
