How to make them "stick" to top?

Problem can solve by using Panels + View.
Please make sure Views Fluid Grid Module has installed.
Please make sure you have content and image.
Please make sure your content labeled taxonomy.

Part 1
1) Create a Custom Layouts in Panels.
2) Create few column, i make 4 column (and name it, example A,B,C,D / 1,2,3,4 / Dog,Cat,Mouse,Steve Job)

Part 2
1) Create a new View.
2) Name it A,B,C,D / 1,2,3,4 / Dog,Cat,Mouse,Steve Job
3) Format: Views Fluid Grid , play the setting especially the CSS3 option.
4) I am trying to make my site alike Pinterest / Chrome Web Store- Home , i show
Show:Fields Content: Image / Content: Title / Content: Rating.
5) FILTER CRITERIA. Content: Has taxonomy term (= UR TAXONOMY)
6) Duplicate Part 2 Step 1~5, (3 more times) or you can clone view (3more times) and rename it and please do remember change the taxonomy term.

Part 3
1) Add a new Content (Panels)
2) Choose the Custom Layouts you created just now. (Part 1)
3) Click the Customize the page button.
4) Click the Add new panes button, find the Views on left sidebar.
5) Click on (A,B,C,D / 1,2,3,4 / Dog,Cat,Mouse,Steve Job).
6) Repeat.

Better Idea
1) Play the image style.
2) Fixed Sidebar. Only Content Scrollable

Review
I am not a coder / themer. This is my way to solved this problem. If someone have better idea please teach me~ thx ya~
Ugly Title if you make this content as your front page.
Due to sort / laying in column with taxonomy, content cannot mix.
