I would like to design a demo ad banner that is used as the 'default' ad for an ad server that we built. For example, when a Wordpress blogger adds an ad to their site, this ad will be the placeholder before the real banner becomes live. In addition, this banner will display for administrators of the site so that they do not abuse their real advertisers.
In general, we need this ad to be 'responsive' - meaning, it should work in many different sizes. I envision this to be CSS with text rather than an image. I should be able to edit this ad and change the text if needed. For ads on the smaller side, the font should shrink (or should change to a shorter amount of text). For ads on the larger side, the font should grow somewhat. The format of the ad will be used across thousands of websites, so the primary color should be very neutral (e.g. gray or similar). The name of the product is called 'Advertising Manager for Wordpress'. We do not have a logo (yet) or any real custom formatting, so design is a bit of a blank slate. The initial text to work with on the ad should be: "Advertising Manager for Wordpress"
"Bring quality advertising to your Wordpress blog"
In general, I would like to review these items in the following ad sizes: 728x60, 120x600, 300x250. I will also review larger and smaller formats.
Thanks for your design!
