Why is it compulsory for ("") to be used in an attribute eg. Border = "5" because I tried without using it and it gave nothing

Answer 1

Hi John snow !

"" is compulsory because some attributes can contain multiple values (e.g. class="clowns frogs lampshades car book") and a space separates attributes.

Border ="5" doesn't work because it needs a unit of measure (e.g. px, em, %, etc.)

I hope this helps!
Keep up the good work! :)
