##How does font-family work in CSS

##

body {
	font-family: Verdana, Geneva, Arial, sans-serif;
}

Check if there is Verdana in the client's computer. If so, use Verdana to display the text. If not, check if there is Geneva. If not, check for Arial. If still not, check if there is sans-serif in the client. Font (generally every computer has a sans-serif font. Note: sans-serif is not a specific font) If the font name contains spaces, you can put that Add quotation marks around the name, like this: font-family: "Courier New", Courier;

If I really want users to be able to use the font I specify, but I don’t know if the user has this font

Web font is here!

How to use

#Find a font file: the suffix name is woff, svg, eot, otf, ttf

1. To place this font on the web, you can use Google's font hosting service, which is free

2. Add the @font-face attribute in CSS

   @font-face {
   	font-family:"Emblema One";
   	src:url("www.某网站.com");
   }/*那个网址就是字体URL */

At this time, it is equivalent to creating a font named Emblema One on the user machine

3. Use it like a local font. Note that the place where you use the font must be @font After -family

#The disadvantage of this is that loading the font will take a while, so the first time a customer visits your website and he does not have this font, he will Take a moment

Adjust the font size

There are three font units: px (pixel), %, em (which is a multiple, em=% divided by 100 )

h1 {
	font-size:220%;
}

There is also a way to specify the font size - keywords (xx-small, x-small, small, medium, large, x-large, xx-large)The size represented by each keyword is not necessarily certain, this has something to do with the client

So, how should I specify the size of the text

First of all, you can define the text size of through keywords. Through keywords, you can get the default size on the client side, which is the commonly used size on the other side.

After that, use percentage or em to adjust the size of other text (such as first-level titles) relative to the text size of . It is not recommended to use px pixels here

Font size, although you can accurately determine the size of the text, scaling will not be supported in older versions of IE browsers

Change font thickness

There are five keyword sizes, namely: bold (bold), bolder (thicker), inherit (inherit the thickness of the previous level), lighter (thinner), normal ( Ordinary)

There is also a way to set the font-weight to a number between 100 and 900 (a multiple of 100 )

Add style to the font

There are four types: inherit (inherit dad), italic (italic), normal (normal), oblique (inclined)

The difference between italic and oblique is that the former uses the italics of this font and is displayed in the font file, while the latter directly italics the regular words. . . But it seems to be about the same

颜色

Demo设置的颜色

body {
	background-color:red;
	background-color:rgb(80%, 40%, 0%);
	background-color:rgb(204, 102, 0);
	background-color:#66ccff;
}

这是四种设置颜色的方法，第一种是关键字，这个一般是小学生在用的吧，支持的颜色不多

第二种是使用rgb（red、green、blue）百分比，那些百分比意思是依次是红/绿/蓝的量（怎么说呢，越大就越含有这个颜色）

第三种和第二种相似，只不过从0%~100%改成了0~255

最后一种是十六进制码，意思是：

前两个代表红的十六进制、中间两个是绿的、最后两个是蓝的

把十六进制转成10机制就变成了第三种设置颜色的方法了

对于文本和背景，要使用对比度比较大的颜色，这样可读性才好

文本装饰（text-decoration）

    不多说，直接看效果：blink inherit line-through none overline underline
