经常会在GitHub上项目介绍的README.md文件中看到许多漂亮的标签，这些标签可以显示version、stars、license等信息
我们可以通过 https://shields.io/ 这个网站在线制作图标，填写label、message、color三个字段，点击Make Badge就可以生成图标，还有其他功能可以自己去体验。
我们也可以通过 HTML + CSS 来实现：
CSS
.github-badge {display: inline-block;border-radius: 4px;text-shadow: none;font-size: 12px;color: #fff;line-height: 15px;background-color: #ABBAC3;margin-bottom: 5px;}.github-badge .badge-subject {display: inline-block;background-color: #4D4D4D;padding: 4px 4px 4px 6px;border-top-left-radius: 4px;border-bottom-left-radius: 4px;}.github-badge .badge-value {display: inline-block;padding: 4px 6px 4px 4px;border-top-right-radius: 4px;border-bottom-right-radius: 4px;}.github-badge .bg-brightgreen {background-color: #4DC820 !important;}.github-badge .bg-orange {background-color: #FFA500 !important;}.github-badge .bg-yellow {background-color: #D8B024 !important;}.github-badge .bg-blueviolet {background-color: #8833D7 !important;}.github-badge .bg-pink {background-color: #F26BAE !important;}.github-badge .bg-red {background-color: #e05d44 !important;}.github-badge .bg-blue {background-color: #007EC6 !important;}.github-badge .bg-lightgrey {background-color: #9F9F9F !important;}.github-badge .bg-grey, .github-badge .bg-gray {background-color: #555 !important;}.github-badge .bg-lightgrey, .github-badge .bg-lightgray {background-color: #9f9f9f !important;}
