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” />

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” />

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	5ff5b82c7d63ca4a4f53f58c49f11459Link to index web page5db79b134e9f6b82c0b36e0489ee08ed

##Link to the previous directory File

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

##1

d541a63e5727f05e7aeed11bc804f5eeLink ccc web page5db79b134e9f6b82c0b36e0489ee08ed

##

Link to files in the upper 2-level directory

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

1	##b379be21ec6fc3c62a9f063c9f6e41a0Link ccc web page5db79b134e9f6b82c0b36e0489ee08ed

Files that link to lower-level directories

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

##44f283f423cfa317273a885fbf458ba5Link bbb web page5db79b134e9f6b82c0b36e0489ee08ed##Files in the 2nd level directory under the link

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

##1

##5369512f3e1ec3ef408e335044021bbeLink aaa webpage5db79b134e9f6b82c0b36e0489ee08ed

# # 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
