How to create a CSS3 property for each corner?


The revolutionary impact of CSS3 on web design cannot be overstated. This modern technology has not only enriched the visual appeal of web pages but also enhanced user engagement. Among the myriad of features that CSS3 offers, the creation of distinctive CSS3 properties for each corner of a web element stands out as a significant breakthrough.

To create a CSS property for a corner, we will use 5 different methods using −

  • Border-radius property

  • Individual corner properties

  • Clip path property

  • Mask image property

Approach 1 - Using Border-radius Property

By utilizing the border-radius property in CSS, one can elegantly curve the edges of an HTML component. The rounding of each corner is regulated by the values allocated to this property. This method is effortless to implement and is compatible with all contemporary browsers. Its advantage lies in the fact that it allows for the creation of an aesthetically pleasing interface for your website or application.

Algorithm

  • Step 1 − Deinfe CSS class called “box”

  • Step 2 − Add width, height, and background color to the class.

  • Step 3 − Use the “border-radius” property to set different radii for each corner of the box.

  • Step 4 − Add <div> element with class “box” inside in the HTML body.

Example

<!DOCTYPE html>
<html>
<head>
   <title>CSS3 property for each corner using border-radius property</title>
   <style>
      .box {
         width: 200px;
         height: 200px;
         background-color: #000;
         border-radius: 10px 20px 30px 40px;
      }
   </style>
</head>
<body>
   <div class="box"></div>
</body>
</html>

Approach 2 - Using Individual Corner Properties

The methodology proposed here shares similarities with the antecedent one, yet it diverges by employing distinct properties for each vertex of the element. By doing so, this methodology accords the wielder greater leverage over the extent of curvature for each corner. The distinct advantage of this method is that it enables the wielder to attain more intricate designs by combining varying values for each corner property.

Algorithm

  • Step 1 − Deinfe CSS class called “box”

  • Step 2 − Add width, height, and background color to the class.

  • Step 3 − Use the “border-top-left-radius”, “border-top-right-radius”, “border-bottom-left-radius,” and “border-bottom-right-radius” to set radius specific radius of the corner.

  • Step 4 − Add <div> element with class “box” inside in the HTML body.

Example

<!DOCTYPE html>
<html>
<head>
   <title>CSS3 property for each corner using individual corner properties</title>
   <style>
      .box {
         width: 200px;
         height: 200px;
         background-color: #E5E5E5;
         border-top-left-radius: 10px;
         border-top-right-radius: 20px;
         border-bottom-right-radius: 30px;
         border-bottom-left-radius: 40px;
      }
   </style>
</head>
<body>
   <div class="box"></div>
</body>
</html>

Approach 3 - Using The Clip-path Property

As technology continues to advance so too do our methods for creating and manipulating shapes. One exciting new option involves adjusting polygon corners using precise coordinate inputs. This customizable approach offers unparalleled control and flexibility in design. Best of all - all modern browsers support this method meaning that your creativity knows no bounds when using this innovative design tool. So break free from the constraints of standard shapes and unleash your creative potential with clip-path!

Algorithm

  • Step 1 − First, define a CSS class “box” in <style>

  • Step 2 − Add width, height, and background color to the class(box).

  • Step 3 − Use the “clip-path” to create a polygon shape, with each corner defined by the percentage of the box.

  • Step 4 − Adding class(box) into the <div> element.

Example

<!DOCTYPE html>
<html>
<head>
   <title> TutorialsPoint - How to use clip-path property</title>
   <style>
      .box {
         width: 200px;
         height: 200px;
         background-color: blue;
         clip-path: polygon(10% 0, 100% 0, 100% 100%, 0 100%);
      }
   </style>
</head>
<body>
   <div class="box"></div>
</body>
</html>

Approach 4 - Using the Mask-image Property

One technique that can be used to create unique and creative designs for your website or application involves utilizing the mask-image property in CSS. This property enables you to create a mask that either reveals or conceals certain parts of the element. By employing a gradient as the mask image, you can achieve the desired shape for your element. This technique is compatible with all modern browsers and allows you to create more intricate shapes beyond simple rounded corners. The main advantage of this method is that it allows coders to add more creativity and design in the web pages.

Algorithm

  • Step 1 − Set the width, height, and background in the style tag for the button.

  • Step 2 − Use the "mask-image" property to create a gradient mask for the box, with the top left corner transparent and the bottom right corner black.

  • Step 3 − Use the "-webkit-mask-image" property as well for compatibility with older versions of the Safari browser.

  • Step 4 − Add class “box” to the <div> tag and print the output.

Example

<!DOCTYPE html>
<html>
<head>
   <title>CSS3 property for each corner using mask-image property</title>
   <style>
      .box {
         width: 200px;
         height: 200px;
         background-color: black;
         -webkit-mask-image: linear-gradient(to bottom right, transparent 50%, black 50%);
         mask-image: linear-gradient(to bottom right, transparent 50%, black 50%);
      }
   </style>
</head>
<body>
   <div class="box"></div>
</body>
</html>

Conclusion

When it comes to crafting CSS3 properties for the corners of an element, there exist a penalty of approach that can be used. The conventional technique involves the use of the border-radius property, which enables the specification of each corner individually. However, there are several alternative approaches available, such as utilizing the clip-path property, pseudo-elements, and SVG shapes.
