问题描述
为了使我的网站具有响应性，我使用了这样的媒体查询
For making responsive my website I'm using media queries like this
@media screen and (max-width: 320px){code}
@media screen and (max-width: 480px){code}
@media screen and (max-width: 640px){code}但是当我尝试测试我的网站时，我遇到了一些问题.一种问题是@media 320px 没问题，但是当我将网页 320px 重新调整为 480px 或 640px 时，默认情况下 320px 即将到来，而其他两个查询不起作用.即使我正在尝试 min-width:320px 但结果是一样的.现在我该怎么办?我的另一个问题是:最大宽度和最小宽度有什么区别?我应该在什么时候使用哪一个?
but when I try to test my website there is some issue I've facing. One kind of issue is @media 320px is alright but when I re-size my webpage 320px to 480px or 640px by default 320px is coming and other two queries not working. Even I'm trying with min-width:320px but result is same. Now what should I do?My another question is: What is the different between max-width and min width? and Which one should I use when?
也试过这个.代码:
@media screen and (min-width: 320px){code}
@media screen and (min-width: 480px){code}
@media screen and (min-width: 640px){code}完全响应式代码，
代码:

}推荐答案
那是错误的代码..@media 屏幕和(最小宽度:320px){此代码将在屏幕 320px 及以上运行如果你把代码放在这里当然这段代码将在 480px 和 680px 下运行}
That's wrong code..@media screen and (min-width: 320px){this code will run at screen 320px and aboveif you put the code here of course this code will run at 480px and 680px}
top 阻止该代码来自 480px 和 680px弄成这样@media screen and (min-width: 320px) and (max-width: 479px){这里的代码}
top prevent that code from the 480px and 680pxMake it like this@media screen and (min-width: 320px) and (max-width: 479px){the code here}
