CSS媒体查询：最大宽度和最大高度

Question

I want to use AND condition in media query. I use the the following code, but it didn't works

@media screen and (max-width: 995px AND max-height: 700px) {
}

Answer 1

逻辑运算符前后缺少右括号和右括号

@media (max-width: 995px) and (max-height: 700px) { ... }

Answer 2

The correct and simpliest way to write this is:

@media screen and (max-width: 995px) and (max-height: 700px) {

}

Answer 3

Use a comma to specify two (or more) different rules:

@media screen and (max-width: 995px) , screen and (max-height: 700px) {
 ...
}

From https://developer.mozilla.org/en/CSS/Media_queries/

...In addition, you can combine multiple media queries in a comma-separated list; if any of the media queries in the list is true, the associated style sheet is applied. This is the equivalent of a logical "or" operation.
