I'm trying to position an element by percentage but it didn't work out for me, it worked only when I used pixels.
Here is my code:
var x=document.getElementById("fir")
x.style.position = "absolute";
x.style.left = 10%
x.style.top = 10%
If I assigned to x.style.left any number followed by nothing it works fine but if I put percentage after the number like it's shown in the code above it doesn't work. Any ideas on how can I use the percentage to position this element?
Those values are supposed to be strings:
x.style.left = '10%';
x.style.top = '10%';
Otherwise, the % sign is interpreted as the remainder operator, leading to unexpected results or syntax errors (depending on your use of semicolons).
You'd have to assign it as a string. You're syntax is invalid, because 10% means something in JavaScript, so it's actually parsing x.style.left = 10%x.style.top = 10% since JS ignores whitespace.
Like bfavaretto said, you need to assign the values as strings:
x.style.left = '10%';
x.style.top = '10%';
and make sure you add your semicolons. :)
The % is CSS syntax, not javascript syntax and you need to wrap it in quotes:
var x=document.getElementById("fir")
x.style.position = "absolute";
x.style.left = "10%";
x.style.top = "10%";
