For the purpose of this exercise I created a quick button using Adobe Illustrator. The dimensions of the canvas used are: 150 width x 35 height (in pixels). This is not a tutorial in Adobe Illustrator but quick changes that you might want to consider are the button’s color and shape. Make something that stands out so that users will find it. If your site has a certain typography as well, this would be a great opportunity to match the settings within any of the image-creation software you are using. Keep in mind that the font size that renders within your site will not match exactly inside Adobe Illustrator, Canva, Photoshop, etc.
This is because the button made from any of the image-creation software will render and be saved as an image rather than a dynamic font. It is important to save the final button as an image in .png format, preferably with a transparent background. If you cannot save the image with a transparent background, make sure that the button’s background color matches that of your site (where the Gravity Form will be embedded).
