How to change source code of page? using selenium and java

Question

I have source code of page like this:

<header style="position: fixed;">

When I use my script on java, I can't execute click action, because my element locate under the header. And I have an error:

Element is not clickable at point (482, 10.116668701171875). Other element would receive the click...

I need to change source code of page to the next view:

<header style="position: absolute;">

Consider, please, this is bad practice for testing. You have to test product as it is — Rudziankoŭ

Yes, I know. I don't test the product. I do program for myself. — GoldenScrew

You can't change the source code of a page after the fact. It doesn't work that way. — BoltClock

To set the style attribute on the first header tag:

((JavascriptExecutor)driver).executeScript(
    "document.getElementsByTagName('header')[0].style='position: absolute;'");

But a better solution would be to scroll the element at the top or bottom:

((JavascriptExecutor)driver).executeScript(
    "arguments[0].scrollIntoView(true);", element);
