Mathematica Use a rule variable for AxesStyle->20

[Swamp Thing]

TL;DR Summary

Why doesn't this work:
axs = AxesStyle -> 20;
Plot [ Sin[x], {x,0,10}, axs ]

How to use a variable rule, e.g. axs = AxesStyle->20 , to set the AxesStyle ? The code in the summary gives this error:

"Options expected (instead of axs) beyond position 2 in Plot[x x,{x,0,10}, axs]. An option must be a rule or a list of rules."

Isn't that "axs" a legit rule?

Plot has the attribute HoldAll so axs is left unevaluated. You need to use Evaluate[axs] to force evaluation despite the HoldAll
