How to set body css

Before we begin, let’s briefly introduce the <body> element. In an HTML document, the <body> element is the main part of the document, which contains all visible content in the document. Since the <body> element is the core part of the entire page, its CSS style needs to be carefully designed to ensure that the entire page presents the best effect.

By setting the background-color or background-image attribute, you can set the <body> The background color or image of the element. Among them, background-color is used to set the background color, and background-image is used to set the background image.
body {
background-color: #f7f7f7;
background-image: url("example.png");
background-repeat: no-repeat; /* 如果启用了背景图片，该属性指定图像是否重复填充整个页面。no-repeat意味着背景图片只应在页面上显示一次 */
background-size: cover; /* 如果启用了背景图片，该属性指定背景图片应如何缩放以填充整个页面 */
}Set font related properties
By setting font-family, font-size, font-weight and other properties , you can set the font, font size, thickness, etc. of the visible text in the <body> element.
body {
font-family: "Open Sans", sans-serif; /* 设置字体类型为Open Sans或sans-serif */
font-size: 16px; /* 设置字体大小为16像素 */
font-weight: 400; /* 设置字体的粗度。400表示正常粗度，700表示加粗 */
line-height: 1.5; /* 设置行高为1.5倍字体大小 */
}Set text alignment
By setting the text-align attribute, you can set the text alignment for all content on the page. The attribute value can be one of left, center, right, and justify.
body {
text-align: center; /* 将页面上所有内容的文本对齐方式设置为居中 */
}Set page width and height
By setting the width and height properties, you can set the width and height of the page. Note that if the height attribute is specified, the scroll bars on the page may not work properly.
body {
width: 960px; /* 设置页面宽度为960像素 */
height: 100%; /* 设置页面高度为100% */
}Set page margins
By setting the margin attribute, you can change the distance between the <body> element and the browser window.
body {
margin: 0; /* 设置页面边距为0 */
}Set the page color
By setting the color attribute, you can control the color of the text on the page.
body {
color: #333; /* 设置页面文字颜色为深灰色 */
}Set page link color
You can set the page by setting the color and text-decoration attributes under the a element. Links are colored and underlined.
a {
color: #0078e7; /* 设置链接颜色为蓝色 */

}
a:hover {
