After mastering the basic HTML tags, you need to categorize them to use the appropriate HTML tag for each case. Let's dive into the following article!

I. Classification of HTML Tags

HTML tags are divided into 3 basic blocks

1. None

This block does not display its internal content.

For example: <html>, <head>, <title>, <meta>, <link>, <script>, <style> ..

2. Block level

This block displays its internal content and spans the entire width of the browser.

For example: <body>, <h1>, <p>, <ul>, <form>, <table> ...

3. Inline

This block displays its internal content and its width depends on the length of its internal objects. And it lies on one line.

For example: , <img>, <a>, <b>, <i>, ...

HTML tags within the <body></body> tags are typically block and inline types.

II. How to Convert Blocks

1. Convert from block to inline

Use CSS with the display: inline property.

2. Convert inline to block

Use CSS with the display: block property.

III. Block Conversion Example

Before block conversion

<div>Thẻ Block level</div>
<br>
<span>Thẻ Inline</span>

<style type="text/css">
  div{
    border: 1px solid #000;
    margin: 5px;
    font-size: 30px;
    padding: 5px;
  }
  span{
    border: 1px solid red;
    margin: 5px;
    font-size: 30px;
    padding: 5px;

  }
</style>

After block has been converted to inline: specifically, add the display: inline attribute to the CSS of the div tag.

<div>Thẻ Block level</div>
<br>
<span>Thẻ Inline</span>

<style type="text/css">
  div{
    border: 1px solid #000;
    margin: 5px;
    font-size: 30px;
    padding: 5px;
    display:inline;
  }
  span{
    border: 1px solid red;
    margin: 5px;
    font-size: 30px;
    padding: 5px;

  }
</style>
