can i know the utility of the banner, whether it will used in website as a header or on the sides?

This will go on the top of the webpage horizontally much like the banners shown on the first slide of the PowerPoint

Hay. Which size of banner you do need?

It should be a web banner on the top of a webpage placed horizontally. Please see the powerpoint slide 1 for examples of the colors and look that is needed.

Hello all,

Please make sure that your banner ads submissions match the same look and color scheme of the banner ads in slide 1 of the powerpoint that was attached to the contest post.

Thanks
Trang
