How to disable page zoom in my code? I mean zooming like this:
Note: I only want it to work in chrome.
Here is the code:
*{
overflow: hidden;
}
.container {
overflow: hidden;
justify-content: center;
align-items: center;
}
.number-ticker {
position:absolute;
overflow: hidden;
top:0px;
left:0px;
color: #D9D9D9;
font-size: 2em;
font-family: Roboto Light;
overflow: hidden;
height: 1.1em;
background-color: transparent;
}
.number-ticker .digit {
overflow: hidden;
float: left;
line-height: 1;
transition: margin-top 0.75s ease-in-out;
text-align: center;
}
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Number Ticker</title>
<meta name="viewport" content="width=device-width,initial-scale=1">
<link rel="stylesheet" href="number-ticker.css">
</head>
<body>
<div class="container">
<div class="number-ticker" data-value="10"></div>
</div>
<script src="number-ticker.js"></script>
</body>
</html>
I have used these in HTML head with no success...
<meta
name='viewport'
content='width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0'
/>
and this one:
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />
But unfortunately, it still zooms... !!! Am I missing something?
I have seen pages that don't zoom at all... So I know there should be a working way ...
I've had this problem before, too, and I think Chrome ignores "user-scalable=no" (at least on desktops).
Check out this answer:

For those who may encounter this annoying problem. you only need to use vh and vw in all of your sizes (fonts, elements, etc...) instead of px and em.... those units do not follow page zoom!

I was learning CSS variables and doing some basic stuff.
/* Variables names must start with -- */
/* They are accessed with var(--name) */
:root {
--clr: blue;
--bgc: whitesmoke;
}
div{
height: 20vh;
display: flex;
justify-content: center;
align-items: center;
font-size: 50px;
background-color: var(--bgc);
margin: 50px;
}
.hello{
color: var(--clr);
}
.world{
color: var(--clr);
}

When I ran the HTML using live-server in VS code.
I got a third and extra div out of nowhere.
which had the following properties
The extra div (and its inner div) is injected by the live server you are using.
While its inner div has display:none so you don't see it, your CSS has set a height and background color on all divs. This means the outer injected div is visible.
It picks up the background-color: var(--bgc) and the variable --bgc has been set as whitesmoke in root.
You could try running your code just from your browser on your PC and you should see just the Hello and World divs without anything extra being injected.
I have the below HTML. For some reason the page is being rendered with the head as text like:
Document
* { display: block; width: 300px; } textarea { height: 300px; }
My Form
I've been searching for an explanation and think it could be because there is an error in the code in the head tag, so the never gets called and it is treated as part of the body, but I can't see any problem with it and VSCode doesn't show any errors.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Document</title>
<style>
* {
display: block;
width: 300px;
}
textarea {
height: 300px;
}
</style>
</head>
<body>
<h1>My Form</h1>
<form></form>
</body>
</html>
You can't use display, width and some more properties in "* (universal selector)". Replace * with body selector, it will work :)
I run your code on my system and the header is coming out bold just like it should... maybe you have to clear your browser cookies or try to open the code on an incognito window
.......
then for the
Document
{ display: block; width: 300px; } textarea { height: 300px; }
that is showing, i guess its an error so i removed the "*" and everything works fine... the working code is below
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Document</title>
<style>
{
display: block;
width: 300px;
}
textarea {
height: 300px;
}
</style>
</head>
<body>
<h1>My Form</h1>
<form></form>
</body>
</html>
I want to make this code good for all devices. If I open it with like a smartphone, it looks very bad.
If you can tell me something to improve too, I would appreciate it!
Here is my index and stylesheet.
Thanks!

It says there is too much code and I need to add more details, but I don't know what to write ^^' so I'm just typing some random things.
One trick is to make absolutely everything relative to the viewport. That way you at least get a properly responsive site on all window aspect ratios.
Whether or not it looks OK on all sizes is something to be considered once you've done this - for a simple design, for example with lots of stuff just centered, you should not need to go into media queries.
You can't make a circle by having width in % and height in %, they are %s of different things so you won't get the underlying square you need. Think about using vmin for the units here and giving them each say 3vmin and see how it works out.
You can even define your font sizes in terms of vmin and they will adjust along with everything else (though be aware that going very very small wont work on some browsers).
So, if you find yourself using px, stop and reconsider.
Also look up more 'modern' ways of doing things like achieving centering and space filling. e.g. flex. Check that everything you are using is both standard and not deprecated. For example using HTML for formatting such as '<center'> isn't now the thing.
For the future, start thinking mobile first when you do a design - but as I say the design you have shown so far should be fine on a smaller viewport if you head for vmin.
edit your meta tag to this:
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />
You can't simply improve like this. You have to add a meta tag for view port in HTML like: <meta name="viewport" content="width=device-width, initial-scale=1.0">In CSS you have a feature named media query like
#media screen and (min-width: /*Your size in which you want the thing to change*/930px) {
body {
/*Your command like mine is*/
background-color: black;
}
}
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
body{
background-color: red;
}
</style>
</head>
<body>
<h1>Hello world!</h1>
</body>
</html>
The above code will change when the size will be decreased. You have to make one for yourself. This is my tip to use query string.
I created a cocos2d-javascript game and am testing it on Chrome. The HTML of the webpage is
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Testing</title>
<link rel="icon" type="image/GIF" href="res/favicon.ico"/>
<meta name="viewport" content="width=100%, initial-scale=1">
<meta name="apple-mobile-web-app-capable" content="yes"/>
<meta name="full-screen" content="yes"/>
<meta name="screen-orientation" content="landscape"/>
<meta name="x5-fullscreen" content="true"/>
<meta name="360-fullscreen" content="true"/>
<style>
body, canvas, div {
-moz-user-select: none;
-webkit-user-select: none;
-ms-user-select: none;
-khtml-user-select: none;
-webkit-tap-highlight-color: rgba(0, 0, 0, 0);
width: 100%;
height: 100%;
margin: 0px;
}
</style>
</head>
<body style="padding:0; margin: 0; background: #000; width:100%; height:100%; margin: 0px;">
<script src="res/loading.js"></script>
<canvas id="gameCanvas" width="100%" height="100%"></canvas>
<script src="frameworks/cocos2d-html5/CCBoot.js"></script>
<script cocos src="main.js"></script>
</body>
</html>
As you can see, I set it up so that the canvas will fit the whole page. This is how the game looks (it is by default 500x500):
If I resize the window, the canvas will generally resize correctly. But sometimes it will have some sort or margin:
What is wrong? I imagine the problem is the HTML itself, rather than cocos2d.
It only seems to occur with Chrome. Firefox seems fine.
I am using Mac OSX Yosemite.
Try:
*, html {
margin:0 !important;
padding:0 !important;
}
And I would suggest removing the properties inside the body style attribute(just for cleanliness), and leaving just properties inside the style tag inside the head.
The HTML div for the navigation bar design in CSS will not work.
CSS
/* CSS Document */
*{
margin: 0px;
padding: 0px;
}
.clear {
clear:both;
height:0px;
}
body {
background:url(../images/bg.jpg) no-repeat scroll center top #13120d;
margin: 0;
padding: 0;
font-family: Tahoma;
font-size: 13px;
}
#header_menu_bg {
background: url('../images/navigation.png') no-repeat center top;
height: 198px;
width: 737px;
}
This is just a short example.
HTML
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-gb" lang="en-gb">
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8"/>

<link rel="stylesheet" type="text/css" href="styles/main.css"/>
<link rel="shortcut icon" href="favicon.png"/>
</head>
<body>
<div id="header_menu_bg">
Any help will be much appreciated!
Make sure the URL to your image is correct.
Place the URL in between ' or " tags (url("../images/navigation.png"))
Add a width to your div, f.e. width: 200px;
EDIT: When looking at your full HTML, you also need to close your <body> and <html> tags.
Your full code will look like this:
HTML:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-gb" lang="en-gb">
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8"/>
<meta name="robots" content="index, follow"/>
<meta name="keywords" content="bla"/>
<meta name="description" content="bla"/>
<title>WEBSITE</title>
<link rel="stylesheet" type="text/css" href="styles/main.css"/>
<link rel="shortcut icon" href="favicon.png"/>
</head>
<body>
<div id="header_menu_bg"></div>
</body>
</html>
CSS:
*{
margin: 0px;
padding: 0px;
}
.clear {
clear:both;
height:0px;
}
body {
background-color: #13120d;
margin: 0;
padding: 0;
font-family: Tahoma;
font-size: 13px;
}
#header_menu_bg {
background: url('http://placehold.it/737x198') no-repeat center top;
height: 198px;
width: 737px;
}
DEMO: JSBin (JSFiddle doesn't seem to work at the moment)
You need to assign it a width attribute.
#header_menu_bg {
background: url(../images/navigation.png) no-repeat center top;
height: 280px;
width: 200px; }
EDIT
Check in the console log, to see if there are issues with the browser finding your image. Perhaps you have the wrong path.
EDIT 2
Close your <body> and <div> tags.
Assuming you have referenced the css file correctly and no error in your html coding structure I suggest clearing your browser cache.
background: url(../images/navigation.png) no-repeat center top;
you need "" or '' like this:
background: url('../images/navigation.png') no-repeat center top;
probably this helps you
The following css works and puts an image in the DIV. Fiddle is not working at the moment and I can't put a link for it now.
#header_menu_bg
{
background-image: url('fnordware.com/superpng/pngtest16rgba.png');
height: 32px;
width: 32px;
}
You either have a wrong url or something else is wrong if this css doesn't work for you.
Try this :
Download the sample image from Here and save it as bg.jpg.
Create a new folder and put the 2 below files & a image in same folder.
HTML (index.html)
<!DOCTYPE html>
<head>
<title>WEBSITE</title>
<link rel="stylesheet" type="text/css" href="main.css"/>
</head>
<body>
<div id="header_menu_bg">
</body>
</html>
CSS (main.css)
body
{
background-color: #13120d;
margin: 0;
padding: 0;
font-family: Tahoma;
font-size: 13px;
}
#header_menu_bg
{
background: url('bg.jpg') no-repeat center top;
width: 280px;
height: 500px;
}
