Creating an oval cutout shape using CSS in a div element

Question

Creating an oval cutout shape using CSS in a div element

I am currently facing some challenges creating the design depicted in the image above, particularly with the oval shape. Let me provide an explanation:

The menu bar is designed as a div with a subtle linear gradient that transitions from dark grey to a lighter transparent grey
The company logo image has a transparent background and will be positioned on top of the menu bar
The oval cutout should match the oval shape of the logo and feature a transparent gap that reveals the background color (which varies across different pages; orange is used here as an example)

Despite several attempts using a radial gradient, I have been unsuccessful. I managed to create a circular cutout but struggled to make it oval, and encountered difficulties in incorporating the linear gradient as well. Here's the code snippet I attempted:

.circle {
    height: 10em;
    background: radial-gradient(circle 50px at 50% 100%, transparent 50px, rgba(84, 82, 94, 0.8) 50px);
    background: -webkit-radial-gradient(50% 100%, circle, transparent 50px, rgba(84, 82, 94, 0.8) 50px);
}

Once the cutout shape and gradient are successfully implemented, the logo will overlay the entire design.

If you have any suggestions or solutions on JSFiddle, they would be greatly appreciated. Thank you!

EDIT 2: I managed to resolve the issue by making slight adjustments to the design. Thanks to those who provided feedback. I created some jQuery code to address this problem - now, when the colored area scrolls out of view, the oval border and header border will adapt to the color of the top section instead of remaining transparent.

Check out this Live Demo to get started.

Please note that I have included a subtle animation to demonstrate the transparency between the island and the cutout div.

HTML Structure:

<div class="cutout">
    <div class="island">
        <div id="circleText">Circle Text </div>
    </div>
</div>

CSS Styling:

.cutout {
    height: 10em;
    background: radial-gradient(ellipse 200px 150px at 50% 100%, 
                                transparent 100px, #555 50px);
    position: relative;
}
.island {
    position: absolute;
    left: calc(50% - 150px);
    bottom: -50%;
    width: 300px;
    background: radial-gradient(ellipse 200px 150px at 50% 50%, 
                                silver 90px, rgba(0, 0, 0, 0) 50px);
    height: 10em;
}
.island > div {
    position: absolute;
    left: 80px;
    right: 80px;
    top: 30px;
    bottom: 30px;

    background: rgba(fff, 0, 0, 0.2);
    padding: 5px;    
    text-align: center;    
}

#circleText {
    padding-top: 30px;
    font-size: 1.5em;
}

Answer №5

If you want to achieve this effect, consider combining three different backgrounds: one radial in the center and two linear ones on the sides.

Creating a seamless transition between the two types of gradients can be challenging; it works best when the gradient is very smooth.

.back {
    height: 100px;
    width: 1000px;
    padding: 0px;
    background-image: radial-gradient(200px 100px ellipse at 50% 100%, transparent 70px, 
               rgba(100, 100, 100, 0.8) 73px, 
               rgba(80, 80, 80, 1) 198px), 
    linear-gradient(180deg, rgb(80, 80, 80), rgba(100, 100, 100, 0.8)), 
    linear-gradient(180deg, rgb(80, 80, 80), rgba(100, 100, 100, 0.8));
    background-size: 200px 100px, 40% 100%, 40% 100%;
    background-repeat: no-repeat;
    background-position-x: 50%, 0%, 100%;
    background-position-y: 100%;
}
