Create a Detailed Calculator Interface with the Appearance Panel

In the following tutorial you will learn how to create a detailed calculator interface by using the Appearance panel, gradients and duplicated shapes. It’s a great tutorial for those who like to avoid using the Pen Tool (P), so let’s get stuck in!
Step 1
Create a New document with the dimensions of 600 pixels by 600 pixels and then click on the Advanced button. Select RGB, Screen (72ppi) and make sure that the "Align New Objects to Pixel Grid" box is unchecked before your click OK.
Enable the Grid (View > Show Grid) and the Snap to Grid (View > Snap to Grid). Next, you’ll need a grid every 5px. Go to Edit > Preferences > Guides > Grid, enter "5" in the Gridline every box and "1" in the Subdivisions box.
You can also open the Info panel (Window > Info) for a live preview with the size and position of your shapes. Do not forget to replace the unit of measurement to pixels from Edit > Preferences > Unit > General. All of these options will significantly increase your work speed.
