CSS Question

CSS Media Queries For Mobile Devices Not Working

I am working with media queries to start making my site more responsive. However, the media queries work perfectly fine on my PC (Chrome) but when viewing on a mobile device (iPad and iPhone) the media queries don't seem to take effect. I have the viewport tag in the head but am guessing I'm missing something else....

CSS

@media (min-width:320px) {
/* smartphones, iPhone, portrait 480x320 phones */
#mainText {
color: pink;
}
}
@media (min-width:481px) {
/* portrait e-readers (Nook/Kindle), smaller tablets @ 600 or @ 640 wide. */
#mainText {
color: blue;
}
}
@media (min-width:641px) {
/* portrait tablets, portrait iPad, landscape e-readers, landscape 800x480 or 854x480 phones */
#mainText {
color: red;
}
}
@media (min-width:961px) {
/* tablet, landscape iPad, lo-res laptops ands desktops */
#mainText {
color: yellow;
}
}
@media (min-width:1025px) {
/* big landscape tablets, laptops, and desktops */
#mainText {
color: green;
}
}
@media (min-width:1281px) {
/* hi-res laptops and desktops */
#mainText {
color: purple;
}
}


HTML

<meta charset=utf-8>
<meta http-equiv=X-UA-Compatible content="IE=edge">
<meta name="viewport" content="width=device-width,initial-scale=1.0">

<div id="mainText">
<h1>Text</h1>
<h2>Text</h2>
</div>

Answer

There seems to be a filter in your css

filter: brightness(1%);

Now because you're not adding any vendor prefixes for webkit, chrome is just deciding to ignore it. You can either remove this rule or add the following to your css.

-webkit-filter: brightness(1%);
filter: brightness(1%);

Cheers and Happy coding!
