Also... They don't work because Steam (like every other standard page) doesn't use non-breaking spaces...
You can replace the normal space with Alt + 255 (which is non-breaking space).
But that's not all, Steam's font isn't monospaced (because they are typographically inappropriate), monospaced fonts are 100% necessary for vanilla ASCII art. This means different characters have different sizes, to compensate for that you can use different sizes of space to align them. (I always copy those spaces from Google search)

Personally I'm not really a fan of "Comment for Comment" but I like to make text art so maybe if you ask for something specific I might be able to make it for you...

Are there any active communities outside of Steam?
What are your favourite ASCII Steam groups?
