Hvis man ikke selv kan skrive webkode, er man i det store og hele overladt til, hvad ens CMS tilbyder af features. Specielt, når server- og klientkode er så 'sammenfedtet', som tilfældet er her.

Det burde ikke være nødvendigt at skrive serverkoden om, når man skal lave en lille ændring i browseren - men gratis CMS'er har desværre ofte den slags besynderligheder.

Jeg tvivler på, du får hjælp i denne kategori. Du kunne prøve at lægge et svar her og acceptere det, så tråden lukkes. Derefter kan du åbne det i denne kategori og se, om der er nogen dér, som har lyst til at rode med det  =)
