How to change the appearance of your website on your computer?

Tell me, please, how can I move the buttons on another website, in a convenient place for me to change was only on my local machine.

Here is an example. Is there a website trading, it has two buttons that I always hit, one is in the top, second at the bottom. In order for them to click, and I either have to turn the wheel to the top or to the bottom.
I know that there is a way to independently swap any blocks on the website. This is done as locally using userscripts, but a lot of information from her eyes run, and where to dig is not entirely clear.

To help narrow your search.

Thanks in advance

stylish - change CSS of the site (your styles will overwrite more).
Select the CSS selector element and add to it
position: fixed;// fixed
top: 0;// top padding
right: 0;// right indent

May need to add !important;
position: fixed !important;

1. Put this extension for chrome. (similar to Greasemonkey)
2. Create a script just for that (You need) of the website (there is a filter: the domains on which the script is active)
3. Find the right object and put this js in the generated script: what do I need to do with it.
