HomeWeb Front-endHTML Tutorialhtml学习整理-0311_html/css_WEB-ITnose

    转了一年还是转回前端了。今天开始认认真真仔仔细细的学习前端内容。首先就是html啦。

    接触html比较晚,14年实习时候才真正接触了Java和html。现在学习的应该叫做html5了。整理一下今天所学的一些标签内容。

    首先说一下DNS:全称Domain Name System,域名系统。是因特网上作为域名和IP地址相互映射的一个分布式数据库。

    URL协议:规定URL地址的格式,URL地址就是网址。

                 规定格式:scheme://host.domain:port/path/filename

                               scheme--定义因特网服务的类型,最常见是http

                                   host--定义域主机,默认主机是www

                               domain--定义因特网域名,如w3school.com.cn

                                   port--定义主机端口号,默认端口号为80

                                   path--定义服务器上的路径,如果省略,则文档必须位于网站的根目录下

                              filename--定义文档/资源的名称

    页面标签:

               块级标签:div、p、ul、ol、dl、li、dt、h1-h6

               行级标签:span、strong、em等

               1.:此标签是定义编码格式。浏览器默认编码格式是中文,如果不设置属性值为UTF-8,会出现乱码情况。还可以通过name和content属性进行网页描述,主要针对网站SEO。

               2.标签:用法1:设置DNS预解析,如

                                   用法2:引入图标 如

                                   用法3:引入css样式 如

              3.标签中,若值为"len"表示页面内容以英语为主,若值为"zh-cn",则表示页面内容以中文为主,此属性有利于搜索引擎或者爬虫对页面的扫描。

              4.标签中,如何使一组radio只能同时选中一个值呢,就是将所有的radio标签中name属性值设为一样即可。

              5.

标签,比较规范的编写格式入下:

 1 <table> 2         <thead><!--此处为表头标签--> 3             <tr> 4                 <th>表头第一列</th> 5                 <th>表头第二列</th> 6             </tr> 7         </thead> 8         <tbody><!--此处为表内容标签--> 9             <tr>10                 <td>内容第一列</td>11                 <td>内容第二列</td>12             </tr>13         </tbody>14     </table>

The official account web page update cache, this thing is simple and simple, and it is complicated enough to drink a pot of it.

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages.

Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
