1. introduce CSS styles in XML.

There are two methods to introduce CSS style sheets in XML. One is to directly embed CSS styles in XML documents, and the other is external introduction (it seems that many of the methods introduced in the WEB have these two methods ). The method for embedding CSS styles in XML is as follows:

Code description: The first line is the header declaration of the XML file. as a well-formatted Xml document, you should add the header declaration information. The second row is the CSS style declaration. xml-stylesheet indicates adding a style sheet to the XML document, type = "text/css" indicates that the type of a style sheet is CSS. The content in the middle of lines 4 and 22nd is the CSS style content, where the fourth row is used to declare and add CSS code, and the fourth row is its closed tag. The following lines are the content of the XML document. After adding the CSS style, open the XML document in IE. The effect is as follows:

The second method is external reference. Example code of external reference:

Code description: Bytes. The following lines are the content of the XML document. The style I wrote in bookstyle.css is as follows:

 1     book{ 2       display:block; 3       background-color:gray; 4       margin:5px; 5     } 6     name{ 7       display:block; 8       line-height:30px; 9     }10     author{11       display:block;12       line-height:30px;13     }14     date{15       display:block;16       line-height:30px;17     }

The only difference between this style and the first style is that the background is changed to gray, and the effect displayed in IE is:

2. set the display effect of the XML document in CSS.

Use the selector in CSS to format the XML document. The selector is generally one or more XML tags, such as the book and name above. the displayed attributes and attribute values are in curly brackets. the attributes and attribute values are separated by colons. With CSS, you can use the dispaly attribute to set whether the label content is displayed. the attribute values include none, block, inline, and list-item. In addition, CSS allows you to set the font, color, text, margin, border, fill, and positioning of XML display. These usage methods are the same as those in HTML. The next article describes how to use XSLT to templated XML documents.
