Introduction to Complex CSS Shapes

Creating rectangles, circles, and rounded rectangles is the basic of CSS. Creating more complex CSS shapes such as triangles, hexagons, stars, hearts, etc. is more challenging but still a simple task if we rely on modern features. But what about those shapes having a bit of randomness and many curves? A lot of names may apply here: random, wavy, wiggly, blob, squiggly, ragged, torn, etc. Whatever you call them, we all agree that they are not trivial to create and they generally belong to the SVG world or are created with tools and used as images.

Thanks to the new shape function, we can now build them using CSS. I won't tell you they are easy to create. They are indeed a bit tricky as they require a lot of math and calculation. For this reason, I built a few generators from which you can easily grab the code for the different shapes. Wavy Divider generator, Fancy Frame generator, Blob generator: all you have to do is adjust the settings and get the code in no time. As simple as that.

Understanding the Logic Behind the Generators

While most of you may be tempted to bookmark the CSS generators and leave this article, I advise you to continue reading. Having the generators is good, but understanding the logic behind them is even better. You may want to manually tweak the code to create more shape variations. We will also see a few interesting examples, so stay until the end.

Notice: If you are new to shape, I highly recommend reading my four-part series where I explain the basics. It will help you better understand what we are doing here. How does it work? While many of the shapes you can create with my generators look different, all of them rely on the same technique: a lot of curve commands.

The main trick is to ensure two adjacent curves create a smooth curvature so that the full shape appears as one continuous curve. Here is a figure of what one curve command can draw. I will be using only one control point. Now let's put two curves next to each other. The ending point of the first curve E1 is the starting point of the second curve S2. That point is placed within.

Creating Smooth Curvature with Curve Commands

To create a smooth curvature, we need to ensure that the ending point of the first curve is the starting point of the second curve. This is achieved by using the same control point for both curves. By doing so, we can create a continuous curve that appears as one smooth shape. The math behind this is quite complex, but the result is well worth the effort.

The curve commands used in the generators are designed to create a smooth curvature by ensuring that the ending point of each curve is the starting point of the next curve. This is achieved by using a combination of mathematical equations and algorithms to calculate the control points and ending points of each curve. The result is a smooth and continuous curve that can be used to create a wide range of complex shapes.

Using the Generators to Create Complex Shapes

The generators provided can be used to create a wide range of complex shapes using the curve commands. By adjusting the settings and parameters, you can create unique and interesting shapes that can be used in a variety of designs and applications. The generators are designed to be easy to use and intuitive, allowing you to create complex shapes without needing to have a deep understanding of the math and algorithms behind them.

The Wavy Divider generator can be used to create wavy and curved shapes that can be used as dividers or separators in designs. The Fancy Frame generator can be used to create complex and intricate frames that can be used to add a touch of elegance to designs. The Blob generator can be used to create random and unique shapes that can be used to add a touch of whimsy to designs.

Manually Tweaking the Code to Create Shape Variations

While the generators can be used to create a wide range of complex shapes, you may want to manually tweak the code to create more shape variations. This can be done by adjusting the mathematical equations and algorithms used in the generators. By doing so, you can create unique and interesting shapes that are not possible with the generators alone.

The code used in the generators is based on a combination of mathematical equations and algorithms that are used to calculate the control points and ending points of each curve. By adjusting these equations and algorithms, you can create new and interesting shapes that can be used in a variety of designs and applications. The math behind this is quite complex, but the result is well worth the effort.

Conclusion and Future Directions

In conclusion, the generators provided can be used to create a wide range of complex shapes using the curve commands. By adjusting the settings and parameters, you can create unique and interesting shapes that can be used in a variety of designs and applications.
