++ bold might benefit from a span tag to not conflict with CSS
++ ID is caps
++ indentation is not clear - what elements contain other elements
++ <br> might benefit from a list
++ <p> might actually be a <ul>
++ <p> closing tag bad
++ redSection not very descriptive id
++ might benefit from some classes
++ information might need to be contained in a form

   This code appears to work. Nonetheless note up to 10 things that look bad to you, including a brief note as to why.
 
   Please consider both minor syntactical issues with the code as it stands, and how the code is structured overall.
+
+  + ES6 should be used
+  + if else statement is hard to read with too many line breaks
+  + reqFlds variable is defined in two different ways - more consistancy is better
+  + return false should be on the same line
+  + conditional statements should have no line break
+  + return statement could just change the submitButtonActive variable
+  + reqFlds seems to not be declared properly
+  + might need document ready for loading purposes
+  + inconsistant semicolons
+  + console logging a string and the funciton?
