Creating adaptable background images with fullpage.js

I'm currently utilizing fullpage.js for parallax scrolling. I'm wondering if there's a way to make the background images adjust responsively when I resize my window.

Check out the documentation here: https://github.com/alvarotrigo/fullPage.js

Here's the specific example I'm referring to: https://github.com/alvarotrigo/fullPage.js/blob/master/examples/backgrounds.html

Despite setting the background-size property to cover for each section in my code, the backgrounds are still not responsive when I resize the window.

#section0,
#section1,
#section2,
#section3{
    background-size: cover;
}   

Answer №1

When it comes to fullpage.js, I may not have much knowledge, but I can definitely help with resizing images based on your window size. To start, download an image and name it sa.jpg.

<html>
    <head>
        <style type="text/css">
        #box{   
            width:100%;
        }
        <!--This class is added to img element to make it responsive -->
        img.responsive{
            max-width:100%;
            height:auto;
        }
        </style>
    </head>

    <body>
         <div id="box">
             <img src ="sa.jpg" class="responsive"></img>
         </div>
    </body>
</html>

The code above places the image within the #box div and adds a responsive class to the img element. This class sets the max-width to 100%, allowing the image to adjust to changes in browser width. It also includes a dynamic height property.

This code snippet ensures responsiveness for the img element.

If you wish to use the background-image CSS property to resize your image based on screen size, you can do so with the following code:

<html>
    <head>
        <style style type="text/css"> 
        #box{   
            width:100%;
            height:100%;
            background-image:url("sa.jpg");
            background-size:100% auto;
            background-repeat: no-repeat;
        }
        <!--img.responsive{max-width:100%;height:auto}-->
        </style>
    </head>
    <body>
        <div id="box"></div>
    </body>
</html>

Answer №2

I find this one to be the most effective

background-position: center;
background-repeat: no-repeat;
background-size: cover;
height: 100%;
