XHTML Getting Started Tutorial: Commonly Used XHTML Tags

<br />Just like an article, our web pages should have clear paragraphs and titles of different importance. This section will introduce the common tags used to implement titles, paragraphs, etc. in XHTML. Title tags <h1> to <h6>
To define a title, we can use the tags from <h1> to <h6>, and their corresponding end tags are </h1> to </h6>. The font size of <h1> to <h6> decreases in order, and the importance also decreases gradually. The browser will automatically leave a blank line above and below the title. Paragraph tag <p>
To define a paragraph, use <p> and </p>. The content between <p> and </p> will be recognized as a paragraph, which is similar to what we usually call a "natural paragraph". Similar to headings, browsers also add a blank line before and after the start and end of a paragraph. Line break tag <br /> (<br>)
When we want to write text on a new line but don't want to start a new paragraph, we can use the <br /> tag. The <br> tag is also an empty tag and needs to be added with a "/" to comply with XHTML requirements. Horizontal dividing line tag <hr />(<hr>)
The tag for implementing a horizontal dividing line is <hr />. Like the <br> tag, <hr> is also an empty tag. In order to comply with XHTML rules, a "/" needs to be added. (There is a dividing line below)

Notes
Proper use of the four tags introduced above can make users who browse your web pages feel that the web pages have a clear hierarchy, while comments can make you feel that the hierarchy is clear when reading the source code of your own web pages, so that you will not be confused. The content between  is the comment content, which will not be displayed on the web page. See how we insert comments in the following exercise example. Practice Example Now open the web page we saved in the previous section and practice some important tags learned in this section. Remove "This is my first <b>webpage</b>." in <body></body> and enter the following content: <h1>Service Announcement</h1>
<hr />
<h2>I am currently providing the following services to primary school students and parents across the country:</h2>
<h3>Services for Students</h3>
<p>
Writing homework for winter and summer vacations (math cannot guarantee that there are no mistakes, Chinese cannot guarantee that there are no typos, and you can ask someone else to write English homework)
<br />If you help bully students below the fourth grade, you will be charged an additional fee.
<br />The Parents Association will help impersonate parents.
</p>
<h3>VIP Service</h3>
<p>Anyone who purchases all three services will be automatically upgraded to VIP. We will create a personal homepage for you free of charge, which fully complies with W3C's XHTML standards and ISO2009~. </p>

After saving the changes, browse the web page to confirm that your web page is the same as this page, and you are done.
