Second This method is indeed effective, but I already stated it in advance when asking the question. It does not use the given fixed height and cannot destroy the existing code structure (remove the doctype declaration).
The first method is different from the question. The question is a Table, and the td is across rows. Trying this method did not work.

Oh. Then there is no need for height:100%. This attribute is only effective when the parent defines the height.

You just use position:absolute;top:50%, and then adjust it according to the height: The height of the content block is written as margin-top: - content block height 1/2

Oh. Then there is no need for height:100%. This attribute is only valid when the parent defines the height.

Just position:absolute;top:50%, and then write margin-top:- content block height 1/2 according to the height of the content block

Absolute positioning cannot be used either. The content in the second row is variable, and there will be many such TABLEs.
In fact, the function I want to achieve is very simple, which is to add two left border lines of different colors to the td of multiple TABLEs. It would save trouble if there was only one.

td:nth-child(odd){border-left:2px solid red}td:nth-child(even){border-left:2px solid blue}

<!DOCTYPE html><html><head><title>无标题页</title><style type="text/css">/*CSS3 nth-child() 选择器*/td:nth-child(odd){border-left:2px solid red}td:nth-child(even){border-left:2px solid blue}</style><script type="text/javascript" src="http://lib.sinaapp.com/js/jquery/1.9.1/jquery-1.9.1.min.js"></script><script type="text/javascript">/*$(document).ready(function(){	$("#mytable").find("td").css("border-left", "2px solid red");	$("#mytable").find("td:odd").css("border-left", "2px solid blue");});*/</script></head><body><table id="mytable">  <tr>    <td> </td>    <td> </td>    <td> </td>	<td> </td>  </tr></table></body></html>

td:nth-child(odd){border-left:2px solid red}td:nth-child(even){border-left:2px solid blue}

<!DOCTYPE html><html><head><title>无标题页</title><style type="text/css">/*CSS3 nth-child() 选择器*/td:nth-child(odd){border-left:2px solid red}td:nth-child(even){border-left:2px solid blue}</style><script type="text/javascript" src="http://lib.sinaapp.com/js/jquery/1.9.1/jquery-1.9.1.min.js"></script><script type="text/javascript">/*$(document).ready(function(){	$("#mytable").find("td").css("border-left", "2px solid red");	$("#mytable").find("td:odd").css("border-left", "2px solid blue");});*/</script></head><body><table id="mytable">  <tr>    <td> </td>    <td> </td>    <td> </td>	<td> </td>  </tr></table></body></html>

This is not right Yes, it is to achieve a column with two left border lines of different colors, so my code above uses a single column spanning two lines. You can open the part I commented in the header and take a look. The screenshot effect:

Beyond HTML: Essential Technologies for Web DevelopmentApr 26, 2025 am 12:04 AM

To build a website with powerful functions and good user experience, HTML alone is not enough. The following technology is also required: JavaScript gives web page dynamic and interactiveness, and real-time changes are achieved by operating DOM.

What are boolean attributes in HTML? Give some examples.Apr 25, 2025 am 12:01 AM

Boolean attributes are special attributes in HTML that are activated without a value. 1. The Boolean attribute controls the behavior of the element by whether it exists or not, such as disabled disable the input box. 2.Their working principle is to change element behavior according to the existence of attributes when the browser parses. 3. The basic usage is to directly add attributes, and the advanced usage can be dynamically controlled through JavaScript. 4. Common mistakes are mistakenly thinking that values need to be set, and the correct writing method should be concise. 5. The best practice is to keep the code concise and use Boolean properties reasonably to optimize web page performance and user experience.
