Ik heb ooit dit als voorbeeld gekregen. Plak het in een test.html en zie je de effecten als je je browser op je laptop of desktop verkleint. Van telefoon tot groot scherm. Makkelijk een css van te maken
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
.example {
padding: 20px;
color: white;
}
/* Extra small devices (phones, 600px and down) */
@media only screen and (max-width: 600px) {
body {
background-color: lightblue;
}
}
/* Small devices (portrait tablets and large phones, 600px and up) */
@media only screen and (min-width: 600px) {
body {
background-color: blue;
}
}
/* Medium devices (landscape tablets, 768px and up) */
@media only screen and (min-width: 768px) {
body {
background-color: red;
}
}
/* Large devices (laptops/desktops, 992px and up) */
@media only screen and (min-width: 992px) {
body {
background-color: green;
}
}
/* Extra large devices (large laptops and desktops, 1200px and up) */
@media only screen and (min-width: 1200px) {
body {
background-color: yellow;
}
</style>
</head>
<body>
