When a user bookmarks or adds your website to their home screen on an iOS touch screen device an Apple Touch Icon is used. If you do not have an icon specified Apple will use a screenshot of your website often resulting in an unrecognizable square. Instead of displaying a substandard icon created by Apple to your end-users, we will teach you how to create a custom Apple Touch Icon for your responsive website.
Step 1: Create the Apple Touch Icon
The first step is to create your Apple Touch Icon in Photoshop or any image editor of your choice. Save it as a PNG file at the size of 180 pixels by 180 pixels and named “apple-touch-icon.png”.
