<button onclick="hideAll()">Show all</button>
<button onclick="javascriptHide">Hide all</button>

Your hiding function is called hideAll(), but you are calling a nonexistent function above. Similarly your show all function is calling hideAll() while you do not have any routines to show all divs written.
I would recommend that you rethink the whole thing, avoid inline functions and start with basic JavaScript and algorithms section on FCC

thats true now its working perfect like you said I only needed to add one more else if

function show(dv){
   hideAll();
   if(dv == '1'){
            document.getElementById("content1").style.display = "block";
   }else if(dv == '2'){
              document.getElementById("content2").style.display = "block";
   }else if(dv == '3'){
              document.getElementById("content3").style.display = "block";
   }
   else{
        document.getElementById("content4").style.display = "block";
   }
}

thanks alot
