回退/响应式CSS样式
回退/响应式CSS样式
提问于 2015-09-18 01:02:22
我刚刚升级了我的网站以包含响应式样式，但当我上传更改时，回退(原始/流体)样式不起作用。它只使用最小宽度的响应样式。我做错什么了？
我的网站是http://jcwebandgraphic.com/

因为两个部分都被定义为最小宽度，所以当显示区域超过1000px时，两个部分都将被应用，而当它超过300px时，将只应用最小宽度:300部分。
由于这两个部分都已应用，因此浏览器将求助于标准css规则来确定相似样式的优先级。(参见http://www.w3.org/TR/2011/REC-CSS2-20110607/cascade.html#cascade)
如果你想更明确，你可以指定：
@media screen and (min-width: 300px) and (max-width: 999px)在此之后，您的响应式样式将停止应用。
如果我理解你正在寻找什么，它将需要嵌套@media查询的能力，但它不受支持。例如：
@media screen and (max-width:999px)
{
@media screen and (min-width:300px)
{ }
@media screen and (min-width:600px)
{ }
@media screen and (min-width:900px)
{ }
}这样，您的响应样式将停止在999px，但它们将累积到这一点？我相信在逻辑上实现这一点的唯一方法是使用LESS或SCSS。这将编译你的css，并按照你试图避免的方式重写它……我认为你能做的最好的事情是：
@media screen and (min-width:300px) and (max-width:999px)
{ }
@media screen and (min-width:600px) and (max-width:999px)
{ }
@media screen and (min-width:900px) and (max-width:999px)
{ }Stack Overflow用户

或者更好的方法是尝试这样的东西：
@import url(responsive.css) screen and (max-width: 999px);在responsive.css中：
@media screen and (min-width:300px)
{ }
@media screen and (min-width:600px)
{ }
@media screen and (min-width:900px)
{ }这是在我看到的另一个帖子中提出的：Nesting @media rules in CSS
