A nit pick about the style sheet: Why is the font size for the
body of the page set to 75%? .... Yes, I know that most users don't
change the font size in their browser preferences, but the default
font isn't overly large.
The default font-size on modern browsers is 16 pixel which is
overlay large imho, - a waste of space. Screen fonts are usually
12px(75%), 13px(81.25%;) or 14 px (87.5%). I agree that 75% is too
small for normal text and should be reserved for annotations etc. I
usually use 81.25% for normal text. That all depends on fonts,
colors, line-height etc. but 13 or 14px usually fit.
Blueprint is nice, it take care of typography.
But defaults are way small for a full text content.
In my mind they have set defaults to suite designers.
Anyway, it simple to compute some new values :
in lua :)
-- Font setting
-- in % change all font size set 1em value
data.BASE_FONT_SIZE = content.BASE_FONT_SIZE or 75 --75% = 12px
with default setting => 1em = 12px
-- in em (BASE_FONT_SIZE); vertical grid step = LINE_HEIGHT *
FONT_SIZE
local DEFAULT_LINE_HEIGHT = content.DEFAULT_LINE_HEIGHT or 1.5 --
12px*1.5 = 18px
data.DEFAULT_LINE_HEIGHT = DEFAULT_LINE_HEIGHT
local DH = DEFAULT_LINE_HEIGHT
data.DEM = DH.."em"
-- Take css selector,
-- font_size in em : multiple of BASE_FONT_SIZE
-- line_height,margin_bottom : multiple of DEFAULT_LINE_HEIGHT
-- + extra style string
local function
mk_step(css_selector,font_size,line_height,margin_bottom,extra)
margin_bottom = margin_bottom or 1
extra = extra or ""
return css_selector.." {font-size:"..font_size.."em;line-
height:"..(DH*line_height/font_size)..";margin-bottom:"..
(DH*margin_bottom/font_size).."em;"..extra.."}\n"
end
local function mk_all_step(t)
local result = {}
for i,s in pairs(t) do
table.insert(result,mk_step(i,unpack(s)))
end
return table.concat(result)
end
-- Take css selector, size multiple of BASE_FONT_SIZE + extra style
local default_step = {
h1={ 3 ,2 ,1 ,""},
h2={ 2 ,2 ,1 ,""},
h3={ 1.5 ,1 ,1 ,""},
h4={ 1.2 ,1 ,1 ,""},
h5={ 1 ,1, 1, "font-weight:bold;"},
h6={ 1 ,1, 0, "font-weight:bold;"},
[".small"]={ 0.8, 1 ,1 ,""},
[".large"]={ 1.2, 1 ,1 ,""},
}
if type(content.STEP) == "table" then
for i,s in pairs(content.STEP) do
default_step[i] = default_step[i] or {}
for j,v in ipairs(content.STEP[i]) do
default_step[i][j] = v
end
end
end
data.STEP = mk_all_step(default_step)
