How to draw drop shapes using CSS?

Problem description: In web design, how to use CSS to draw the shape of a water droplet is an interesting and practical requirement. Water drop shapes are not only common in design, but their implementation methods can also help developers better understand the border-radius properties in CSS. This article will discuss how to create a drop-like shape using CSS.

In the Q&A community, a user asked the question: How to draw the following water droplet shape using css?

To address this problem, there is a way to use pure css to achieve a similar but not exactly the same drop shape by adjusting the border-radius property. Although it may be more precise to use canvas or svg directly, the css method is still worth a try. Here is an example of using css implementation:

 
  
    <style>
      .water-drop {
        width: 100px;
        height: 260px;
        background-color: #3498db;
        border-radius: 50% 50% 50% 50% / 20% 20% 80% 80%;
      }
    </style>
  
  
    <div class="water-drop"></div>
  

Through the above code, we can see a graph that is close to the shape of a water droplet. Among them, the border-radius property is set to 50% 50% 50% / 20% 20% 80% 80%, which makes the top of the element round and the bottom sharper, forming the shape of the droplets. While this approach does not completely copy the water droplets in the reference image, it provides a simple and fast solution.

It should be noted that if the accuracy of the graph is high, drawing using canvas or svg may be a better choice. These technologies are able to provide more complex and precise shape control. However, for some simple and inefficient designs, using css is still an effective method.
