该做和不该做的

使用标题样式

学会在描述性的标题下组织你的段落，并对这些标题应用“风格”. 这个习惯会让任何人更容易浏览你的文档并找到他们想要阅读的部分, 一个被称为“可扫描性”的属性."

在大多数软件应用程序和web内容管理系统中, 您可以使用格式工具栏上的样式菜单突出显示要制作为标题的文本并应用内置样式.
如果你正在开发一个网站, 你也可以使用CSS在一个地方设置网站上所有标题的样式.

在你的软件中使用样式菜单.
不要使用文本选项样式标题.

是否:将标题级别与内容结构匹配

浏览网页

使用一级标题表示每页的标题、主题或目的.
在网页的浏览器页面标题中重复全部或部分第1级标题.
使用二级标题来指示文档的每个主要部分.
使用三级标题来表示子章节.
使用第4级、第5级和第6级标题来表示子章节.

数码文件

Some people use multiple level 1 headings and mark the document title with a tag.</li> <li>其他人则认为，文档标题应该是一级标题，因此是唯一的标题1.</li> </ul><p>在 <a
