Step 1

Hit CTRL + N to create a new document. Select Pixels from the Units drop-down menu, enter 600 in the width and height boxes then click on theAdvanced button. Select RGB, Screen (72ppi) and make sure that the Align New Objects to Pixel Grid box is unchecked before you click OK. Enable the Grid (View > Show Grid) and the Snap to Grid (View > Snap to Grid). For starters you will need a grid every 5px, so simply go to Edit > Preferences > Guides > Grid, enter 5 in the Gridline every box and 1 in the Subdivisions box. You should also open the Info panel (Window > Info) for a live preview with the size and position of your shapes. Do not forget to set the unit of measurement to pixels from Edit > Preferences > Units > General. All these options will significantly increase your work speed.

Pick the Rectangle Tool (M) and focus on your Toolbar. Remove the color from the stroke; then select the fill, and set its color at R=160 G=163 B=168.

Make sure that your rounded rectangle is still selected, open the Appearance panel (Window > Appearance), select the existing fill and go to Effect > Stylize > Inner Glow. Enter the properties shown in the following image and click OK.

Select this new fill, open the Gradient panel (Window > Gradient) and simply click on the gradient thumbnail to add the default black to white linear gradient. Make sure that your shape stays selected and keep focusing on the Gradient panel. First, set the Angle at 0 degrees. Next, select the left gradient slider and set the color at R=0 G=0 B=0 (black); then select the right gradient slider and use the same color. Focus on the gradient bar and simply click on it to add a new gradient slider. Make sure that this new slider is selected, set its color at R=255 G=255 B=255 (white), focus on the Location box (from the Gradient panel) and drag it at 50%. Keep in mind that the white numbers from the Gradient images stand for Location percentage. Add two new sliders for your gradient then use the color and Location attributes shown in the following image. Return to the Appearance panel, make sure that the second fill is still selected, lower its Opacity to 50% and change the Blending Mode to Soft Light.
