Setting the viewpoint

In order to create a responsive website, add the following code to all your web page

HTML Code:

<meta name="viewport" content="width=device-width, initial-scale=1.0">

Enter fullscreen mode Exit fullscreen mode

This will set up the viewport of your page. Which will give instruction to your browser on how to control the page’s dimensions and scaling.

Responsive images

This are images that scale nicely to fit any browser size. Using the width property If the CSS width property is scaled to 100%, the image will be responsive and scale up and down

HTML Code:

<img src="google.jpg" style="width:100%;">

Enter fullscreen mode Exit fullscreen mode

Responsive Text Size

The text size can be set with a "vw" unit, which means the viewport width". That way the text will follow the size of the browser window

HTML Code:

<h1 style="font-size: 10vw"> Hello World</h1>

Enter fullscreen mode Exit fullscreen mode

Media Queries

In addition to resize text and images, it is also common to use media queries in responsive web pages.

HTML Code:

<style>
    .left, .right {
        Float:left;
        Width: 20%;
    }
    .main {
        Float: left;
        Width:60%;
    }

    /* use a media query to add a breakpoint at 800px */
    @media screen and (max-width: 800px){
        .left, .main, .right {
            Width:100%; /* the width is 100%, when the viewport is 800px or smaller */
        }
    }
</style>
Enter fullscreen mode Exit fullscreen mode
