I’m from the future, this thread is a top search result, and both of these links don’t work any more (c.f. XKCD:979, but not quite as dramatic 
)
Anyway, here’s a mwe for “inner ticks with labels,”
using CairoMakie
fig = Figure()
ax = Axis(
fig[1, 1],
limits = (-10, 10, -5, 5),
xticks = [-3, 0, 3],
xtickalign = 1.0,
xticklabelpad = -25
)
save("inner_ticks.png", fig)
