console.log在控制台打出css样式的文字及图片

console.log增强api

谷歌开发者中心上面关于谷歌浏览器控制台console.log()的文档

Format	Specifier
%s	Formats the value as a string.
%d or %i	Formats the value as an integer.
%f	Formats the value as a floating point value.
%o	Formats the value as an expandable DOM element (as in the Elements panel).
%O	Formats the value as an expandable JavaScript object.
%c	Formats the output string according to CSS styles you provide.

可以看到，通过占位符%c,可以对输出到console控制台的文字进行CSS控制。

格式如下：

console.log("%c需要输出的信息 ", "css 代码");

输出3D TEXT

console.log("%c3D Text"," text-shadow: 0 1px 0 #ccc,0 2px 0 #c9c9c9,0 3px 0 #bbb,0 4px 0 #b9b9b9,0 5px 0 #aaa,0 6px 1px rgba(0,0,0,.1),0 0 5px rgba(0,0,0,.1),0 1px 3px rgba(0,0,0,.3),0 3px 5px rgba(0,0,0,.2),0 5px 10px rgba(0,0,0,.25),0 10px 10px rgba(0,0,0,.2),0 20px 20px rgba(0,0,0,.15);font-size:5em")

彩色背景文字
