Use imitation italic or bold?
font-synthesis

Instruct the browser in how to handle fonts that don't have proper italic and bold variants.
Property values
Font families that don't have dedicated files for italic variants and bold weighting are sometimes synthesized by the browser's renderer to approximate the appearance of italic or bold. With some fonts this is undesirable.
Ues one of these settings:
none | Do not synthesize bold or italic |
weight | Bold may be synthesized if the actual font weight is not available |
style | Italic may be synthesized if the actual italic variant is not available |
Examples
font-synthesis: none;
