Boost Your CSS Skills with These 5 Unknown Properties
A useful tool for managing a website's design is CSS, or Cascading Style Sheets. Many CSS properties, such as margin, padding, color, and font-size, are well-known to web developers, but there are many other properties that are less well-known that may improve your designs and accelerate your code. With code samples and real-world applications, we'll delve into five of these overlooked treasures in this blog article. Upon completion, your CSS toolbox will have been expanded with more capabilities that will enable you to produce web pages that are more visually attractive, dynamic, and efficient.
1. CSS - clip-path
The clip-path property allows you to create complex shapes by clipping an element. This can be particularly useful for creating non-rectangular layouts or for adding a unique flair to images and other elements.
Syntax
clip-path: shape;
Example: Creating a Polygon Clip
Let's say you want to clip an image into a hexagon shape. You can use the clip-path property to achieve this effect.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Clip Path Example</title>
<style>
.hexagon {
width: 200px;
height: 200px;
background-image: url('image.jpg');
background-size: cover;
clip-path: polygon(25% 6.7%, 75% 6.7%, 100% 50%, 75% 93.3%, 25% 93.3%, 0% 50%);
}
</style>
</head>
<body>
<div class="hexagon"></div>
</body>
</html>
In this example, we define a div with a class of hexagon and apply the clip-path property to it. The polygon function is used to define the six points of the hexagon.
Practical Applications
2. CSS - scroll-snap
The scroll-snap properties enable you to control the scroll behavior of a container, making it "snap" to predefined points. This is particularly useful for carousels, galleries, and full-screen scrolling sections.
Syntax
/* Container */
scroll-snap-type: x mandatory;
/* Child elements */
scroll-snap-align: start;
Example: Horizontal Scroll Snap
Let's create a horizontal scrollable container that snaps to each child element.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Scroll Snap Example</title>
<style>
.container {
display: flex;
overflow-x: scroll;
scroll-snap-type: x mandatory;
width: 100%;
height: 200px;
}
.item {
flex: none;
width: 100%;
height: 100%;
scroll-snap-align: start;
background-color: lightblue;
margin-right: 10px;
}
.item:nth-child(2) {
background-color: lightcoral;
}
.item:nth-child(3) {
background-color: lightgreen;
}
</style>
</head>
<body>
<div class="container">
<div class="item"></div>
<div class="item"></div>
<div class="item"></div>
</div>
</body>
</html>
In this example, the container has scroll-snap-type set to x mandatory, ensuring it snaps horizontally. Each child element has scroll-snap-align set to start, making sure the scroll snaps at the beginning of each child.
Practical Applications
3. CSS - object-fit
The object-fit property controls how the content of a replaced element, such as an <img> or <video>, should be resized to fit its container. This property is particularly useful for responsive design, ensuring that images and videos maintain their aspect ratio and fit within their containers.
Syntax
object-fit: fill | contain | cover | none | scale-down;
Example: Responsive Image with object-fit
Let's create a responsive image gallery where images cover their containers without distortion.

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Object Fit Example</title>
<style>
.gallery {
display: flex;
flex-wrap: wrap;
}
.gallery img {
width: 300px;
height: 200px;
object-fit: cover;
margin: 10px;
}
</style>
</head>
<body>
<div class="gallery">
<img src="image1.jpg" alt="Image 1">
<img src="image2.jpg" alt="Image 2">
<img src="image3.jpg" alt="Image 3">
</div>
</body>
</html>
In this example, each image in the gallery uses the object-fit: cover property to ensure the images fill their containers without losing their aspect ratio, resulting in a consistent and visually appealing gallery.
Practical Applications
4. CSS - aspect-ratio
The aspect-ratio property sets a preferred aspect ratio for an element, which helps in maintaining the aspect ratio when the element size changes. This is especially useful for responsive design and for elements that should maintain a specific ratio, like videos or images.
Syntax
aspect-ratio: width / height;
Example: Maintaining Aspect Ratio for a Video
Let's ensure a video maintains a 16:9 aspect ratio.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Aspect Ratio Example</title>
<style>
.video-container {
width: 100%;
aspect-ratio: 16 / 9;
background-color: black;
}
.video-container iframe {
width: 100%;
height: 100%;
}
</style>
</head>
<body>
<div class="video-container">
<iframe src="https://www.youtube.com/embed/dQw4w9WgXcQ" frameborder="0" allowfullscreen></iframe>
</div>
</body>
</html>
In this example, the .video-container maintains a 16:9 aspect ratio regardless of its width, ensuring the embedded video fits perfectly.
Practical Applications
5. CSS - backdrop-filter
The backdrop-filter property applies graphical effects such as blurring or color shifting to the area behind an element. This property can create stunning visual effects and is particularly useful for overlays and modal windows.
Syntax
backdrop-filter: none | blur() | brightness() | contrast() | drop-shadow() | grayscale() | hue-rotate() | invert() | opacity() | saturate() | sepia() | url();
Example: Blurred Background Overlay
Let's create an overlay with a blurred background effect.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Backdrop Filter Example</title>
<style>
body {
background-image: url('background.jpg');
background-size: cover;
height: 100vh;
margin: 0;
display: flex;
justify-content: center;
align-items: center;
}
.overlay {
width: 80%;
height: 80%;
background: rgba(255, 255, 255, 0.1);
backdrop-filter: blur(10px);
display: flex;
justify-content: center;
align-items: center;
color: white;
font-size: 2em;
}
</style>
</head>
<body>
<div class="overlay">
Stunning Visual Effect
</div>
</body>
</html>
In this example, the .overlay div has a semi-transparent background and a backdrop-filter with a blur effect, creating a visually appealing overlay with a blurred background.
