I know I had earlier asked this question in the forum, but I had to reboot my site, and somehow, all my posts pertaining to this question have disappeared from the forum. So, I have no option but to reask:
1 How to change the font in Asteroid. I see that the header font is not changing in one browser.
2 How to increase the size of the post grab in the blog excerpt.
3 How to change the color of the bars around the website.
