Media queries not working on Iphone but fine on br

问题:

Hi Im currently using a Boilerplate theme called Bones on a WordPress but Im having problems making the responsive menu work on my Iphone. When I manually resize the menu seems to work

the media query im using is

@media only screen and (min-width: 960px) {

the site im trying to get to work is here:link

Any help would be much appreciated as I have gone to the theme writer and he hasn't responded in days

回答1:

have you used the meta viewport object? Put this in the head of your document

<meta name="viewport" content="initial-scale = 1.0,maximum-scale = 1.0" />

You need to mention Media like this  for iphone and smartphones

/* Smartphones (portrait and landscape) ----------- */
@media only screen 
and (min-device-width : 320px) 
and (max-device-width : 480px) {
/* Styles */
}

/* Smartphones (landscape) ----------- */
@media only screen 
and (min-width : 321px) {
/* Styles */
}

/* Smartphones (portrait) ----------- */
@media only screen 
and (max-width : 320px) {
/* Styles */
}

I just came across an issue where, when I loaded my stylesheet with this:

<link src="mobile.css" media="only screen and (min-width: 400px)" />

and then within mobile.css, I had a couple of styles like this:

@media screen and (min-width: 400px) {
    body {
        background: red;
    }
}

h1 {
    color: blue;
}

and several devices (iPhone, iPad - with a different breakpoint of course, and Galaxy Nexus) did not see the background:red; rule ("nested" media query), only those that were outside of the "inline" media query (h1). Chrome and other browsers were fine with it, however.

This jumped out at me as weird:

@media only screen and (max-width: 480px), only screen and (max-device-width: 480px) { 
    ... 
}

I believe that should be

@media only screen and (max-width: 480px), 
@media only screen and (max-device-width: 480px) { 
    ... 
}

or...

@media only screen and (max-width: 480px) and (max-device-width: 480px) { 
    ... 
}

You might also want to consider moving from XHTML to HTML5 for your doctype.
