Configuration options for CSS parameters such as font, avatar, background image

[epidrome]

Consider adding options in _config.yml as parameters for visual style, because it seems that some users want to change attributes in the CSS such as

• [ ] font (e.g., family, size)
• [ ] avatar image (e.g., transparency, no border)
• [ ] background image (e.g., solid color, responsive size vs clipping)

It is worth assessing current use by existing users, but I guess that there is trade-off between simplicity-features, ie some hacks are best left to advanced users as local changes

@epidrome could you kindly give an example how to modify title font-color in _config.yml?

My modification is somewhat like below, however it doesn't work properly as I expect

# Title and tag line
font-family: "Arial Black", Arial, Helvetica, sans-serif
font-color:  #00FFFF,
font-margin: 200px auto

Thanks
