Scroller is a DotNetNuke module for creating scrolling content such as text or images banners.
The module is based on the marquee element.
Marquee content has many usability problems, because it disctacts the human eye and is constantly moving. Also because of the fact that not the complete marquee content may be visible all the time it may cause printing problems. Last marquee element is not HTML compliant, thus its existance in a web page may cause W3C validation failure. You can read more about marquee element in Wikipedia.
We do not advise the usage of this module when complianse is required!
Concluding, this module:
- it is not HTML compliant but is supported by all browsers (IE, Mozilla Firefox, Chrome, Opera etc.)
- it is lightweight. Its impact is only few bytes (less than 1 kb) and you do not have to include any extended JS to create the scrolling effect. So it is recommended in heavy loaded pages (e.g. online newspapers or blogs).
- if you create small banner ads you can save the content in module settings (this works even if you do not have MS SQL database provider). On the other hand, if you want to create scrollable articles' headers or other bigger content, you can store the content in its MS SQL database table.
- it is cheap; just check it in SnowCovered.
