Learn@UW/D2L - Small Font Sizes May Cause Unread Discussion Posts to Not Appear in Bold
If you select a small font size in your preferences, unread Discussion posts within a topic may not appear in bold.
The minimum font size required for unread discussion posts to appear in bold depends upon the font face selected, browser, and zoom factor selected in your browser.
In general, a font size of at least 11 points should be selected to make unread discussion posts to appear bold with your browser's zoom factor set at 100%.
If unread discussion posts do not appear in bold, try increasing the font size in your preferences, select a different font face, or increase your browser's zoom factor.
Note that the default font is 14 point Verdana which will cause unread posts to appear in bold unless a small zoom size (for example, below 75%) is selected.
