Utilizing React for captivating full-size image backgrounds

Utilizing React for captivating full-size image backgrounds

As a novice, I am faced with the challenge of making a full image background in my react portfolio project. Despite my efforts, I have been unable to achieve the desired outcome.

How can I implement a full image background in React for my portfolio showcase?

* {
margin: 0;
padding: 0;
box-sizing: border-box;
}

body,
html {
    margin: 0;
    font-family: "Poppins", sans-serif;
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
    height: 100%;
}

The styling details are defined in my index.css file:

I have set up a component specifically for the background image:

const background = {
    backgroundImage: `url(${Background})`,
    height: "100%",
    backgroundPosition: "center",
    backgroundRepeat: "no-repeat",
    backgroundSize: "cover",
};

Next, I call this component within my React component:

return (
    <div style={background}>
        <h1> Hello </h1>
    </div>
)

Despite my attempts and research, I am still encountering issues as seen in the following image: https://i.sstatic.net/MP4iC.png

I have explored various methods but have not yet found a successful solution :(

Answer №1

To make sure your application takes up the entire screen, it's recommended to use vh and vw units:

<div style="height:100vh;width:100vw">TEST</div>

In this scenario:

const background = {
    backgroundImage: `url(${Background})`,
    backgroundPosition: "center",
    backgroundRepeat: "no-repeat",
    backgroundSize: "cover",
    height: 100vh;
    width: 100vw
};

If you only set the height to 100%, your background will only fill the container (body).

Consider using this background style:

const bgStyle = {
    backgroundImage: `url(${Background})`,
    height: "100vh",
    backgroundPosition: "center",
    backgroundRepeat: "no-repeat",
    backgroundSize: "cover",
};

Percentages are relative units that will take up 100% of the parent size. Vh (viewport height) is a unit based on the device's size, setting an element's size to equal the full-screen height with 100 vh. Learn more about viewport units here:

It appears that the issue may be stemming from the height of your root element not being sufficient.

To resolve this, you will need to include some CSS to ensure the first element has adequate height:

#app {
   height: 100%;
}

Here is a small example:

const Example = () => {

            const Background = 'https://picsum.photos/200/300';

            const background = {
                backgroundImage: `url(${Background})`,
                height: "100%",
                backgroundPosition: "center",
                backgroundRepeat: "no-repeat",
                backgroundSize: "cover",
            };

            return (
                <div style={background}>
                    <h1> Hello </h1>
                </div>
            )
        }

        ReactDOM.render(<Example />, document.getElementById("app"));

* {
            margin: 0;
            padding: 0;
            box-sizing: border-box;
        }

        body,
        html {
            margin: 0;
            font-family: "Poppins", sans-serif;
            -webkit-font-smoothing: antialiased;
            -moz-osx-font-smoothing: grayscale;
            height: 100%;
        }

        #app {
            height: 100%;
        }

Answer №4

Consider using:

height: 100vh,
width: 100vw,

Instead of:

height: "100%",

This change is important because it ensures that the background covers the entire viewport, which refers to the visible area of a web page for the user, rather than just the component's area.
