What does the meaning of this CSS value mean?

Question

While looking at the source of the webpage, I came across this CSS applied to the range inside the button:

.whatever button span {
    position: absolute;
    left: -1e+7px;
}

What does it mean left: -1e+7px;? Is this some kind of trick I should know about?

Answer 5

This is invalid CSS, according to the W3C validator :

.whatever button span    Value Error : position attempt to find a semi-colon before the property name. add it
.whatever button span    Value Error : left Unknown dimension 1e

If you add the missing ;after position: absolute, you will still get:

whatever button span     Value Error : left Unknown dimension 1e
