:only-child psuedo class not displaying properly in Chrome.

When I followed the instructions in the video with Guil, we are instructed to apply :only-child which gives the properties to the unordered list. When I applied the properties such as font-size and color, the color was omitted but the font size was applied. I then tried this on the Mozilla browser and the color and font size were applied properly. Not sure what is going on but thought I would lets others know I also had this issue.

I ran into the exact same issue. In Chrome it doesn't display properly, but in Firefox and Edge is looks like demonstrated in the video.

'''/* Structural Pseudo-classes------------------ */

li:first-child { background: #52bab3; color: white; }

li:last-child { border: none; }

:only-child { color: #52bab3; font-size: 1.5em; }'''

Chrome is fully compatible with "only-child". It could be you have other CSS that is interfering with the size setting.

To facilitate analysis, always provide the complete code (formatted using Markdown) or make a snapshot of your workspace and post the link to it here.

Your color property is overwritten by the color property of the body element. But I haven't found out how to fix it so far ;-)

Changing the order might help. For items with the same level of specificity, the one that comes last will take effect.
