对Blogger模板的媒体查询是对还是错？

Question

我将要制作一个响应式Blogger模板，我将从屏幕媒体查询开始，但不确定这些是否正确。

    @media(max-width:1960px){
/*For TV screen */
body{min-width:1660px;}
h1{font-size:60px;}
img{max-width:100%; height:auto;}
.sidebar .sidebar.section .widget{width:280px;}
.content-outer, .content-fauxcolumn-outer, .region-inner{min-width:1660px;max-width:1660px;_width:1900px;}}
@media(max-width:1380px){
/* For Desktop Screen */

h1{font-size:50px;}
img{max-width:100%; height:auto;}
