Fine-tuning the visual display within the viewing area

Is there a way to retain the curve at the bottom of an image even after setting its background size to 50vh? The current issue is that the curve gets cropped out when the height is set, resulting in a loss of the desired effect.

.background{
    background-image: url("https://i.sstatic.net/r45nE.png");
    background-repeat: no-repeat;
    height: 50vh;
    /*height: 916px;*/ <!--this is the height of the image-->
}

Answer №1

You have the ability to customize it based on your needs. This particular javascript function is designed to carry out the specified task for you.

var canvas = document.getElementById("myCanvas");
var context = canvas.getContext("2d");
context.beginPath();
context.moveTo(20, 20);
context.bezierCurveTo(20, 100, 200, 100, 200, 20);
context.stroke();
<canvas id="myCanvas" width="300" height="150" style="border:1px solid #d3d3d3;">

Answer №2

To ensure the proper display of your background, it is essential to incorporate the background-size and background-position properties:

.custom-background{
    background-image: url("https://i.sstatic.net/r45nE.png");
    background-repeat: no-repeat;
    background-size: cover;    
    background-position: 0% 100%;
    height: 50vh;
}
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">
    <header>
        <div class="container-fluid d-flex justify-content-center custom-background">

        </div>
    </header>

Answer №3

To customize the background position and size, you can use the following CSS code: 

.background{
    background-image: url("https://i.sstatic.net/r45nE.png");
    background-repeat: no-repeat;
    background-position: center bottom;
    background-size: 100%;
    height: 50vh;
    /*height: 916px;*/ /*this is the height of the image*/
}
    <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">
    <header>
        <div class="container-fluid d-flex justify-content-center background">

        </div>
    </header>

Answer №4

If you are displaying an image as a background and only seeing the top half, you may need to adjust the position of the background in your viewport.

background-position: bottom;
background-size: cover;

Changing the position to "bottom" will display the image from the bottom, while setting the background size to "cover" will help fit the entire image in your viewport.
