body is a tag in HTML, usually written: this style means to define the body and all the styles under the body, that is, if other tags under the body such as div, p or something are not specifically defined, then they will inherit the style defined by the body to display.

So let's talk about what all the styles mean:

font-family: "Songti","Heiti"; This means that the font that defines the text displayed on the page, and if it is not recognized, then it will be displayed in bold.

This is to set the size of the font, em is the unit of font size, and if you understand it simply, em is equivalent to a percentage.

color:red;color is the color of the font, and here the font color is specified as red.

font-weight:bold;It is the definition of whether it is bold or not, and bold means bold, so that the text will be bolded.

text-decoration:underline;It is to define the text style as an underline, and underline is the meaning of an underline. text-decoration and other style options are relatively simple in English and can be understood directly.

This is to define the line spacing of the text, this can also be written as 150%, their effect is the same, usually the default most standardized text line spacing is 150%, and you can also define it according to your own needs such as 20px with unit height.

The first is inline, which is commonly used in learning CSS styles in the past, that is, writing CSS styles into the header information. For example, after setting the background color of the web page, a ** will be added to the header information, and a body style will be added to it.

The second type of inline style is to enter the CSS style directly in the HTML style, for example, you can select the style attribute value after entering the style directly in heading 1.

If you set it again, you need to enter it; Empty a space before selecting a different style attribute value. However, this method is not recommended.

The third type of connection, which is currently the most commonly used, can be used directly for multiple web pages.

Click Create CSS Rule, select the required selector and name in the pop-up New CSS Rule dialog box, select Create Style Sheet File in the Rule Definition, and click OK.

In the dialog box that appears, select the name of the CSS style file and select the folder you want to place.

Then in the CSS style attributes, there is one more connection to the CSS file, and there is an SCC style file on the top of the window, if you want to use this CSS style file in other web pages, as long as you copy the CSS connection ** to other web pages, other web pages can also apply the properties set by this CSS style file, and we can put all the properties of the entire ** web page in this CSS style file. In the future, when you change the ** style, you only need to change this CSS style file.
