How to Add a Gradient on a Stroke in Adobe Illustrator

Adding a gradient on a stroke in Adobe Illustrator can be achieved through the following steps:

1. Open Adobe Illustrator and create a new document or open an existing one.

2. Select the object you want to apply the gradient stroke to.

3. In the toolbar, select the "Stroke" option to activate the stroke panel.

4. In the stroke panel, click on the "Type" drop-down menu and select "Gradient."

5. Next, select the "Gradient" drop-down menu and choose the type of gradient you want to use, such as linear or radial.

6. Adjust the gradient stops and colors as desired using the gradient panel.

7. Finally, adjust the stroke weight to the desired thickness.

Note: It's important to keep in mind that not all stroke types are compatible with gradients. In some cases, you may need to convert the stroke to an outline or expand the appearance of the object in order to apply a gradient stroke.
