Two if statements in a row arent working [closed]

Answer 1

if (content_left = "-100vw") { 

You're setting the value here instead of testing it. Use == or === instead. The same goes for the rest of the if statements.

Your also using outdated content_left values.

  var content_left = $('.content').css('left');

^^ This line should be copied to the beginning of both the moveLeft and moveRight functions.
