</style>web响应式图片的5种实现
在目前的前端开发中，我们经常需要进行响应式的网站开发。本文着重介绍一下弹性图片，也就是响应式图片的解决方案：js或服务端、srcset 、sizes 、picture标签、svg图片
使用现代CSS的响应式版面
通过模块化缩放,使用传统属性和calc()来动态缩放你的字体大小.为字体大小使用百分比.给文本内容和媒体查询使用em,针对不同视口尺寸使用不同缩放值.视口越小,缩放比例越小,使用媒体查询或者media()函数基于视口来改变比例和基础字号
移动端web app要使用rem实现自适应布局:font-size的响应式
rem是相对于根元素html，这样就意味着，我们只需要在根元素确定一个px字号，则可以来算出元素的宽高。
