A brief discussion on the writing method of path when HTML file is introduced into external CSS file


1、 Introduce the basic style of external CSS file

Use the < link > tag to introduce an external style sheet, in which two attributes are usually written:

  • The path of the CSS file is indicated by the attribute
  • Rel = “stylesheet” describes the relationship between the current page and the document specified by the document. That is to say, the document connected by the document is a new table

<link href="style.css" rel="stylesheet" />

2、 Basic rules of path

/Represents the root directory
… /Represents the upper level directory
… /… /Represents the upper two levels of directory
/… Represents the subdirectory
/… /… Represents the next two levels of directory

3、 Examples of common path writing

one index.html and style.css The files are in the same folder


<link href="style.css" rel="stylesheet" />

2. The CSS file is in the same folder as the HTML file


<link href="c/style.css" rel="stylesheet" />

3. The parent folder of HTML and CSS file are in the same folder

As shown in the figure, there are folder B and folder B2 under folder a, style.css In folder C under folder B, index.html It’s in the B2 folder.

  • At this point, the idea of writing the path is: find the path index.html Documents and style.css The common parent folder of the file, seen from the figure, is folder a.
  • First, from index.html File start, that is, at this time in the B2 folder, first find the a folder (the upper level directory of the B2 folder), that is /
  • Then find it in folder a style.css Document, i.e. B / C/ style.css
  • Put together is: a /b/c/ style.css “


<link href="../b/c/style.css" rel="stylesheet" />
