This tutorial aims to guide you on how to manage different screen sizes in hybrid apps. By the end of this tutorial, you'll have a solid understanding of responsive web design techniques that will ensure your app looks good and works well on all devices.
Basic knowledge of HTML, CSS, and JavaScript is required. Familiarity with Bootstrap is recommended but not required.
Responsive web design is an approach to web design that makes web pages render well on a variety of devices and window or screen sizes.
CSS Media Queries are a feature of CSS that allows you to conditionally apply styles based on the properties of the viewer's device and browser.
@media screen and (max-width: 600px) {
body {
background-color: lightblue;
}
}
When the browser's width is 600px or less, the background color changes to light blue.
The viewport meta tag gives the browser instructions on how to control the page's dimensions and scaling.
<meta name="viewport" content="width=device-width, initial-scale=1">
This sets the width of the page to follow the screen-width of the device (which will vary depending on the device).
Bootstrap’s grid system uses a series of containers, rows, and columns to layout and align content.
<div class="container">
<div class="row">
<div class="col">
Column
</div>
</div>
</div>
/* CSS file */
@media only screen and (max-width: 600px) {
body {
font-size: 18px;
}
}
This will change the font size to 18px when the device's screen width is 600px or less.
<!-- HTML file -->
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
</head>
This will set the width of the webpage to follow the screen-width of the device.
<!-- HTML file -->
<div class="container">
<div class="row">
<div class="col-sm">
One of three columns
</div>
<div class="col-sm">
One of three columns
</div>
<div class="col-sm">
One of three columns
</div>
</div>
</div>
This will create a responsive layout with three equal columns.
