Visit github.com/username/username and read the Readme generated by this tool.

Skills icons will always be absolutely huge and fill the screen.

Additionally, sometimes when I made any change to my Readme (even just adding a space), the images would become huge on my profile too.

It seems something changed on Github's end and it prefers style tags instead.

Only the following fix worked:

Instead of:

<img style="margin: 10px" src="https://profilinator.rishav.dev/skills-assets/csharp-original.svg" alt="C#" height="50" />

Do this:

<img style="margin: 10px; height: 50px" src="https://profilinator.rishav.dev/skills-assets/csharp-original.svg" alt="C#"/>

Notice how I changed it to a CSS value instead of its own tag.

(You should still add px like I did for clarity, but that wasn't the cause of this issue)
