element.style.left = 50;
and how can i solve the problem
Thanks

What's a text element?

Probably because it's invalid. Any length value, other than zero (0),
requires a unit. Change it to

element.style.left = '50px';

Replace ".invalid" with ".uk" to reply by e-mail.

Get a reference to the element (e.g.
var element = document.getElementById('elementId');
) and then read
element.offsetWidth
element.offsetHeight

element.style.left = 50;

Make sure element is a reference to an element object and then make sure
you use syntactically correct CSS e.g.
element.style.left = '50px';
