html {font-size:12px}@media screen and (min-width:480px) and (max-width:639px) {html {font-size: 15px;}}@media screen and (min-width:640px) and (max-width:719px) {html {font-size: 20px;}}@media screen and (min-width:720px) and (max-width:749px) {html {font-size: 22.5px;}}@media screen and (min-width:750px) and (max-width:799px) {html {font-size: 23.5px;}}@media screen and (min-width:800px) and (max-width:959px) {html {font-size: 25px;}}@media screen and (min-width:960px) and (max-width:1079px) {html {font-size: 30px;}}@media screen and (min-width:1080px) {html {font-size: 32px;}}

方法二：用js來設定

/*

*** 12為最小字型大小

*** 40為最大字型大小

*** 320螢幕下font-size是12

*/

document.getElementsByTagName(‘html‘)[0].style.fontSize = Math.min(window.innerWidth*12/320,40)+"px";
