/* media queries are always placed beneath the main code
   since the specificity of selectors of media and normal code is same.
   It is by virtue of media queries being /after/ the main code that they are able to override the selectors in main code.
   Also, the order goes from maximum device size to minimum device size when you're using max-width.
   To break the order, just specify @media(width: - px) instead of writing max-width.
   That way, it will apply the specified styles to only that width and not upon the ranges of width
   e.g 768 - <some> px in the case where your last max-width media query was 768.
   Since, in this code,  queries are being applied like this:
   0 - 320px
   320 - 375px
   375 - 425px
   425 - 768px
   For 1024px, we have the main code that we want to be used.
   To get query to apply to ONLY 1440px and not to 768px - 1440px (which would override the 1024px code), 
   we use width instead of max-width */
