Recommendations for Improvement

Normal Priority recommendations

While not absolutely critical, we would like to see Yahoo! improve Yahoo! Mail to support the following CSS properties:

List-style-image: A design can be enhanced by dressing up bullets in a UL. The two most popular methods for making this happen are the default list-style-image and an alternate, more controllable method using background-image and padding. When list-style-image is defined and then not supported, the degradation is minor in that a default bullet is displayed. However, it’s a modest property which, when supported, can greatly enhance a visual design.
