Linear Gradient Creates Jagged Edges in Background Image: How to Smooth the Line

In an effort to create a pointed bottom edge on an image, one may opt for producing two responsive triangles at the base. However, achieving a smooth line in such a design can prove challenging. As mentioned in the original question, linear-gradient employed for this purpose tends to exhibit jagged edges due to its "hard-stopping" behavior.

The solution lies in modifying the color transitions within the gradient. By shifting the starting point of the second color slightly away from the ending point of the first, one can introduce a subtle blur effect. This alleviates the sharp color transition and results in a smoother line.

Referencing the original code, modify the linear-gradient property in the following manner:

.lefttriangle {
  ...
  background-image: linear-gradient(to right top, #ffffff 48%, transparent 50%);
}

.righttriangle {
  ...
  background: linear-gradient(to left top, #ffffff 48%, transparent 50%);
}

By adjusting the stop and start points as shown, the color transition becomes less abrupt, enhancing the smoothness of the line at the triangle's base. It's worth noting that this resolution achieves compatibility with most modern browsers without compromising responsiveness.
