@jiangcaiyang It works if you do it right. It doesn't take LESS variables, but it does work. Odds are the less styles have higher specificity, so your custom CSS rules are not applied. Use !important or something instead. It will certainly benefit you to not be held back due to incompatibility with newer versions of NodeBB in the future.
Even if you did name it, you wouldn't, sadly, be infringing on any copyright as this isn't a video game and/or article of clothing. BUT HOW DID THEY? WHY? CAPS LOCK CONFUSED MODE INITIATED!
