How to Use Our Desktop Template

This template makes building Racer X Online site skins as simple as possible. 

  1. Place your background images in the “Background Images” folder. You can place color, texture, or images here.
  2. Select one background color from the “Background Color” folder (options #1-5).
  3. Select the same color option you chose for the background in Step #2 from the “Background Fade” folder (options #1-5). This will make your image appear to fade into the background. Do not alter this mask. You will notice the correct look of this fade on the next page (SCREEN SIZE: 1900 X 800 image).
  4. Place your foreground text and other content in the “Foreground” folder. Content in this folder must not enter the area between the center guides (indicated with arrows above). Do not alter the folder mask. Do not extend any foreground images in this folder beyond the bottom or sides of this document. You may extend foreground images beyond the top. NOTE: Please make sure all important text is contained within the inner 130 pixels of each side. (You will notice guides to help with this.)
  5. Do not hide, remove, or alter the “Site / Shadows” folder.
  6. Hide the “Hide this before saving” folder.
  7. Please optimize the files as much as possible prior to saving. Use the “Save for Web and Devices” function under the file menu to save. We have already set up the files to ensure you create the correctly sized site-skin files. Please save and send each side separately. Each side should be 450x775.

2x Density Images

2x Density images are very important to include in any web ad campaign ad to ensure your ad creative looks crisp and clear on the end-users display. If you do not include 2x density ads, they will appear blurry and unclear on high-resolution retina display screens.
