关于javascript:HTML文档和文字标签

文字类标签
code is everything！

<!--题目--><h1>一起帮·源栈欢迎您！</h1><h2>飞哥祝你学习提高，早日年薪过万！</h2><!--还能够有h3,h4,h5,h6-->    <!--段落--><p>你感觉这些抉择自身，真的可能决定你的人生成败么？     真正决定成败的，不是你抉择之后的付出和致力么？你只是不敢选！     所以同流合污。你须要精力的力量，所谓勇气。     而勇气，来源于鸡汤（划掉），来源于真心。     只有当你真心想做一件事的时候，你能力迸发出你最大的激情，从而最全力以赴最坚持不懈的投入，因而最有可能取得成功     ——退一万步讲，就算不那么胜利，做着本人喜爱做的事，开开心心一辈子也赚到了。</p><p>同样有用的，还有楷模。楷模的力量是无穷的。</p><!--换行-->我应该扪心自问：<br />我是在做个生意呢，还是在做一件事业？<br /><!--标注--><i>教育是人照亮人。</i><br /><b>我有没有尽我最大的致力，去照亮他们？</b>

以上内容节选于于飞哥的：教学质量还是招生营销？2020年，我理想主义一次，欢送浏览点赞，^_^

留神以上代码还蕴含了以下知识点：

正文
正文不会被浏览器显示进去。

换言之，浏览器不会将正文中的内容出现给用户。

正文个别有两个作用：

阐明解释，同正文的转义。HTML中应用得不多，因为：
调试时当做“删除”应用：和真正的删除相比，它当前能够很不便的找回来！
HTML中应用不多，因为：

HTML逻辑简略，个别不须要正文阐明，也较少调试
正文会减少HTML文件大小，影响性能（尤其是互联网晚期）
但咱们当前学习的C#、SQL和JavaScript，将大量应用正文！

自闭合标签
br就是一个自闭合标签。

如果开始标签和完结标签之间没有/不须要文本，就能够应用自闭合标签（是不是相似于一种简写？）

@找找看@

咱们以后页面用了那些文字标签？

插入：源栈培训：前端：调试神器F12

转义字符
@想一想@

我就想在页面显示大于（>）小于（<）符号，怎么办？

F12，或者，善用搜素引擎（bing：）

字符 转义字符
" "
& &
< <

>
一直开空格(non-breaking space)  
这种可能“原样出现”被某种语言所“占用”符号的特定符号，被称之为“转义字符”（有点绕，但飞哥也没查出个清晰易懂的解释，大家意会吧，^_^）
