</html>The HTML of the page is composed like this. If you look closely at this code, you can look at this.
if(this.style.left=='1600px')this.href='?go='+this.style.left" This code is included in a tag. In addition, you can know that the ID of A tag is "hackme".
Thus, we should change the value of "this.style.left" to '1600px'.
To manipulate it opens the developer tool window.
Then, Modify the code like this.
(Before)
onclick="this.style.left=parseInt(this.style.left,10)+1+'px';
(After)
onclick="this.style.left=1600+'px';
After modifying like this, click 'O' of the page.
Then, you can get to the point of problem 10.
