I take this comment from GP as not criticizing but just showing his/her superiority.
> Making an unfounded assertion that long lines cause eye strain doesn't make your css any better. I certainly don't suffer from such a debilitating limitation. Anyone who does can just make their window narrower, or bump up the font size in their browser.
He/She is certainly not providing any critical feedback.
I do apologize for lashing out, and I don't have any excuse to put in for that.
