I don’t know if this is the best place for this or not but, seriously, learn css.
My team is looking for another front end dude (or dudette) and the repeating theme seems to be:
Oh I know all the new stuff, I know JS, I know React, Redux, whatever else is the new shiny… But when it comes to " how would you lay this out", well that’s when things seem to fall apart.
Myself and 2 other front-enders were like old men, "back in OUR day, to call yourself a front-end developer, you had to know CSS.
But seriously, learn css. I hate gong thru code and seeing bad stuff and knowing I have no time to refactor, it hurts.
