How to limit max width and height to screen size in CSS?
I'm trying to make a php gallery and thats why I need a good Mask, where the pictures later can be shown.
I want the Mask not to be bigger than screen-size. I mean, there must be no scrolling and the whole <body> needs to have just the width and height of the browser windows, so that every child object in <body> is limited to the frame-size of the browser and will be shrunk down if it overflows. I've tried with max-width and max-height on the <body>, but it doesn't work.
Here are the contents of my index.html file:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
<div id="mother">
<div id="header">
<div id="back-link">
<a href="../">Home</a>
</div>
<div id="prev">
<a href="">next picture</a>
</div>
<div id="next">
<a href="">previous picture</a>
</div>
<div id="headline">
<p class="h2">Our Galery</p>
</div>
</div>
<!-- Content -->
<div id="container-bild">
<img src="./bilder/P1130079.JPG" id="img-bild" />
</div>
</div>
</body>
</html>
Here are the contents of my style.css file:
body {
max-width: 100%;
max-height: 100%;
}
/* mother-container */
div#mother {
max-width: 100%;
max-height: 100%;
margin: auto;
}
/* main-container */
#container-bild {
max-width: 100%;
max-height: 100%;
}
/* picture in main-container */
#img-bild {
max-width: 100%;
max-height: 100%;
border: 1px solid #280198;
}
Here is a screenshot of what it looks like:
Answer
To set the height and width to be 100% of the window (viewport) size, use:
height: 100vh;//100% view height
width: 100vw;// 100% view width
.
div {
background-color: blue;
height: 100vh;
width: 100vw;
position: absolute;
top: 0;
left: 0;
color: white;
}<div>some content here</div>
