我知道我不是很擅长html5，但我正在积极学习。我一直难以让我的网站在移动浏览器上做出响应。我能够在计算机上对Web浏览器做出响应。
任何人都可以告诉我如何才能使其响应并向我解释该功能的工作原理？
非常感谢你！

答案 0 :(得分：3)
我的建议是，使用像bootstrap这样的css框架。
https://getbootstrap.com/docs/4.1/getting-started/introduction/
或
如果您不想使用框架，可以使用媒体查询。
/ *手机 - 320x480px * /
@media screen and (max-width: 480px) {
h1{
color: blue;
}
}
/ *平板电脑 - 768x1024px * /
@media screen and (max-width: 1024px) {
h1{
color: red;
}
}
并尝试使用检查响应式视图 http://ami.responsivedesign.is/
答案 1 :(得分：2)
您可以使用屏幕媒体查询使网站响应，并在html文档的头部添加元标记。
媒体查询的工作方式如下：您添加屏幕大小，然后添加其中的样式
@media only screen and (max-width: **your screen size here**) {
div {
color: green;
}
}
