CSS CSS Foundations The Box Model Positioning Properties

Position: Fixed

I created an header element having position: fixed and min-width set to 960px. But, when I resize the browser to a width lesser than 960px, the width of the header element also shrinks. Any solution why is it happening?

Here is the code: header{ width: 100%; min-width: 960px; background: #000; padding: 10px; box-sizing: border-box; position: fixed; }

Hi Shailesh,

Percent (%) is a relative value....since you used width: 100%, it will not matter how small or large the screen gets, the width of your header will fill it 100%.

Play around and see if this works instead.

(1) Set your width to 960px; then (2) Set your min-width to 100%.

NOTE: Percentages are used in "Responsive Layouts" because percentages are relative to the screen size (i.e. cell phone).

Hi Carla,

I removed width: 100%, but still getting the same bug. I think it's happening only because I have used position: fixed. When, I am using a different value for the position property then it perfectly gives results as I expect. But, what about the fixed top navigation bars in Twitter and Facebook?

Thanks
