Media Query Being Ignored - html

I have two logos: one for small screens and one for large ones.
Rather than different resolutions of the same image, these are two very different .png files and thus I can not use a scaling function. In my attempt to use them, I created the following media queries in a .jsp page with the purpose of editing a div box in order to show the files as background-images:
<style>
<meta name="viewport" content="width=device-width, initial-scale=1">
#media (min-width: 1200px) {
.zachery_div {
background: url(/assets/img/LargeLogo.png);
width: 764px;
height: 76px;
float: right;
}
}
#media (max-width: 1199px) {
.zachery_div {
background: url(/assets/img/SmallLogo.png);
width: 262px;
height: 76px;
float: right;
}
}
</style>
However, this only gives me the smaller logo when the width of the window is below 1199px.
If I expand the window to 1200px or above I receive nothing.
Both images are valid because swapping their position allows me to call either one, but never both.
Can any of you tell me what is wrong with my code?

When using mobile first approach (min-width) the smaller values come first, so your code would be:
.zachery_div {
height: 76px;
float: right;
}
#media (max-width: 1199px) {
.zachery_div {
background: url(/assets/img/SmallLogo.png);
width: 262px;
}
}
#media (min-width: 1200px) {
.zachery_div {
background: url(/assets/img/LargeLogo.png);
width: 764px;
}
}
<meta name="viewport" content="width=device-width, initial-scale=1">
Note that meta tag shouldn't be inside style tag. but inside head before style
And since you had repeated properties, I put them outside of #media as they are "standard" across the code

Cannot view media queries on desktop, but able to see it when inspecting the page

I was following a tutorial about media queries. When I open the HTML in Chrome/Firefox, I get a blank page, and nothing displays. When I inspect the page though, the code displays normally and I can see how the media queries work. I tried adjusting the min-width and max-width of the media queries but I still get a blank page in any browser I use. I have posted the original HTML below from the tutorial.
<!DOCTYPE html>
<html>
<head>
<title>Beginners CSS - Chapter 8</title>
<style type="text/css">
* {
margin: 0px;
}
main {
margin: 10px auto;
width: 600px;
padding: 30px;
margin-top: 0px;
background-color: olive;
display: block;
}
#media screen and (max-width: 350px) {
main {
background-color: #88a5e0;
}
}
#media screen and (min-width: 600px) {
main {
background-color: red;
}
}
#media screen and (min-width: 800px) {
main {
background-image: url('images/Reeds-in-Wind-Cinemagraph.gif');
background-repeat: no-repeat;
background-size: cover;
padding-bottom: 400px;
}
}
#media screen and (min-width: 1000px) {
main {
background-image: none;
background-color: #fff;
}
h1,
p {
display: none;
}
}
</style>
</head>
<body>
<main>
<h1>Media Queries</h1>
<p>Media allows you to make your pages to change to fit any device.</p>
</main>
</body>
</html>
The screen width changes when the developer tool is opened on the right/left dock. So, the elements that you saw perhaps are from the min-width 800px media query.
The page when the minimum width is 1000 pixels is not "blank page and nothing displays". You can read from the code below, you're setting the background-color to white, hiding the h1 & p and removing the background-image when the min-width: 1000px.
#media screen and (min-width: 1000px) {
main {
background-image: none;
background-color: #fff;
}
h1,
p {
display: none;
}
}
The page is not blank, according to your code for screens with width more than 1000px you set this styles:
#media screen and (min-width: 1000px) {
main {
background-image: none;
background-color: #FFF;
}
h1, p {display: none;}
}
so the h1 and p1 element will not be displayed and the background will be white,
if you resize the window other media queries happen.
Also by Opening your developer tools you are resizing your window.

making two columns responsive in html

Simple one probably. I've made a webpage and now need it to be responsive to a mobile at 375px;
In the html I have added:
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
My two columns are named in the html as follows:
#columnleft {
float: left;
width: 50%;
text-align: center;
background-color: #E8F8F5;
}
#columnright {
float: right;
width: 50%;
text-align: center;
background-color: #F4ECF7;
}
<div id="columnleft"> ..... </div>
<div id="columnright"> ..... </div>
I know i need to make a media query like this
#media screen and (max-width: 375 px)
But nothing is working. The largest size is 1024 px only these two sizes matter for this project. Nothing in between. I need the two columns to stack up on top of each other rather than side by side
Any advice much appreciated, thanks
make their width 100%
#media only screen and (max-width: 357px) {
#columnleft, #columnright {
width: 100%;
}
}

Table Not Being Styled For Mobile | CSS

I'm experiencing some problems with my two stylesheets.
I've been trying to make my website mobile friendly so I created a separate CSS file for mobile. Like so:
<link rel="stylesheet" type="text/css" media = "screen" href="css/services.css">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" type= "text/css" href="css/mobile/services.css"
media ="only screen and (max-width: 500px)" />
Except I've run into a problem with overiding the main CSS file with the mobile one for a specific problem (only one part is not overriding; everything else is fine).
In "css/services.css" (the main one) I have:
#pricing{
margin: 0px;
}
.pricing_tables{
width: 600px;
margin-bottom: 100px;
}
And in "css/mobile/services.css" (the mobile version) I have:
#pricing{
width: 270px;
}
.pricing_tables{
margin: 0 auto;
width: 270px;
margin-bottom: 30px;
}
Basically, I can't change it to have a smaller width. But I haven't run into any problems until now.
The element I'm trying to change is a table. #pricing is the also set at width:270px
Thanks In Advance!
Is there any reason why you wouldn't simplify your life and combine your two stylesheets into one?
See if this helps you:

CSS
#pricing{
margin: 0px;
}
.pricing_tables{
width: 600px;
margin-bottom: 100px;
}
#media screen and (max-width: 500px) {
#pricing{
width: 270px;
}
.pricing_tables{
margin: 0 auto;
width: 270px;
margin-bottom: 30px;
}

Don't use specific CSS on smaller screens

I have some CSS that makes the whole site content have a marging to the left and right with 5em.
.content {
margin-left: 5em;
margin-right: 5em;
}
However, I want the margin to NOT work(not have a margin) or only have a margin with 1em when I enter the site on a mobile phone or touchpad. I have tried the following code but nothing happens. More specificly, I want this to be activated, and have no margin or only margin on 1em, on the screens that uses the initial scale I have set on every page. And I suppose that its only phones and pads.
#media screen
{
.content {
margin-left: 1em;
margin-right: 1em;
}
}
#media print
{
.content {
margin-left: 1em;
margin-right: 1em;
}
}
#media screen,print
{
.content {
margin-left: 1em;
margin-right: 1em;
}
}
You can use a media query with a specified width to achieve that :
#media (max-width: 640px){
.content {
margin-left: 1em;
margin-right: 1em;
}
}
See here common device width to choose the width you want : http://mydevice.io/devices/
Also don't forget to include the viewport meta in your <head></head> tag to make it works on your phone :
...
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
</head>
...
The syntax that you are using for media query is incorrect.
One must specify the width at which the media query will trigger in other words the width on the screen at which the code inside the media queries that will overwrite the default code.
the syntax for the #media property is
`#media not|only *mediatype* and (*media feature*) {
CSS-Code;
}`
So you must use this code to achieve the desired results :
#media (max-width: 667px){
.content {
margin-left: 1em;
margin-right: 1em;
}
}

#media not working correctly for me

I have a css file that looks like this:
#foo{
width: 35%;
height: 380px;
}
#media only screen and (max-device-width: 480px) {
#foo{
width: 100%;
height: 100%;
}
}
When I run the html from a mobile browser it's not displaying in full screen, any idea what needs to be modified? Ive tried Safari and Chrome and neither seem to apply the changes on the mobile device.
Make sure the meta viewport tag is set with width=device-width:
<meta name="viewport" content="width=device-width, initial-scale=1.0"/>
The only thing i can think of is that the device you're testing on actually has a screen larger then 480px.
Testing your code in a browser by making it smaller on my laptop without "device-" works.
#foo{
width: 35%;
height: 380px;
}
#media only screen and (max-width: 480px) {
#foo{
width: 100%;
height: 100%;
}
}
