The difference between relative paths and absolute paths in HTML

In actual web development, inserting pictures, including CSS files, etc. all require paths. If the file path is added incorrectly, the reference will become invalid (the linked file cannot be browsed, or the inserted picture cannot be displayed, etc.). Many beginners are confused. Below I will introduce relative paths and absolute paths in detail.

HTML relative path

refers to the path relationship with other files (or folders) caused by the path where this file is located.

For example:

The absolute path of file 1.htm is: d:/www/html/1.htm

The absolute path of file 2.htm is: d: /www/html/2.htm

Then: the path of 1.htm relative to 2.htm is: 1.htm

How to use relative links:

If To link to the same directory, you only need to enter the name of the document to be linked, for example:

<a href =”1 htm”>网页链接 </a>
<img  src=”bg.jpg” / alt="The difference between relative paths and absolute paths in HTML" >

If you link to a lower-level directory, you need to enter the directory name first, then add "/", and then enter the file name ,For example:

<a href =”html/ next.htm”>
<img  src=”images/bg.jpg” / alt="The difference between relative paths and absolute paths in HTML" >

If you connect to the upper-level directory, you need to enter "../" first, and then enter the directory name and file name, for example:

<a href = “．．/ www/index.htm”>

Example summary

There are now 4 html files, namely aaa.html bbb.html ccc.html index.html

• ##aaa.html path is: D:/www/adminwang/ The path of html/aaa.html

• bbb.html is: D:/www/adminwang/ bbb.html

• ccc.html The path is: D:/www/ ccc.html

• index.html The path is D:/www/ index.html

link Files in the same directory

For example, the ccc.html file link index.html code is as follows:

1	Link to index web page

##Link to the previous directory File

For example, the code of bbb.html link to ccc.html is as follows:

##1

Link ccc web page

##

Link to files in the upper 2-level directory

For example, the code for linking aaa.html to ccc.html is as follows:

1	##Link ccc web page

Files that link to lower-level directories

For example, the code for ccc.html to link to bbb.html is as follows:

##Link bbb web page##Files in the 2nd level directory under the link

1

For example, the code for linking ccc.html to aaa.html is as follows:

##1

##Link aaa webpage

# # HTML绝对路径 为文件提供的完全路径，包括适用的协议或盘符。也就是你的主页上的文件或目录在硬盘上真正的完整的路径。例如： http://www.adminwang.com/index.htm d:/ www /html/images/bg.jpg 绝对路径没有什么好说的，相对路径掌握了，绝对路径就很简单了。 相关推荐： HTMLa标签的href属性指定相对路径与绝对路径使用方法 html的绝对路径和相对路径怎么使用 php算法实现相对路径的案例
