Conditional Formatting in HTML Tags

Question

Is there any option for using IF-ELSE conditioning in HTML tags

   do something     
      do something            


        

Answer 1

With acknowledgement to Kevin Loney and his javaScript solution, we should also consider CSS conditionals. If the conditional is based on browser-sensing/responsive design, then javaScripting can be bypassed:

show something
show something

"Show something" in the sense that you would merely hide the condition which does not apply. In the example below, "if-part" is shown on mobile devices only. "else-part" is shown on larger screens.

@media screen and (max-width:767px){
    .if-part{display:initial;}
    .else-part{display:none}
}
@media screen and (min-width:768px){
    .if-part{display:none;}
    .else-part{display:initial}
}

This answer offers even more CSS options to consider.
