Prevent div from moving while resizing the page

Question

I'm quite new to CSS and I'm trying to get a page up and running. I managed to successfully produce what I thought was a nice page until I resized the browser window then everything started to move around. I have no idea why this is happening!!

Could someone offer me some advice please. When I resize the window I would like the 'objects' to stay where they are but the window to resize. for example, if I drag the bottom corner of a window up and to the left I'd expect to see what was at the bottom right disapear and scroll bars to appear but the object in the top left hand corner would stay exactly where they are.

Am I making sence ?

Have a look at working condition of my page : http://aimmds1.estheticdentalcare.co.in/

then try to resize the browser window by dragging the right size leftwards . and look at the content in header , and also the menubar .. they jump down ,, the header content was also jumping down then i make overflow: hidden ; .. but as i understand all this is not the right way.

Please find the html and CSS here : http://jsfiddle.net/swati/hCDas/

I already tried prevent div moving on window resize , i tried setting min-width:820px; for div header , that the main containing div.. but that doesnt solve it.

Thanks in anticipation of your help.

Answer 1

1 - remove the margin from your BODY CSS.

2 - wrap all of your html in a wrapper <div id="wrapper"> ... all your body content </div>

3 - Define the CSS for the wrapper:

This will hold everything together, centered on the page.

#wrapper {     margin-left:auto;     margin-right:auto;     width:960px; }

There are two types of measurements you can use for specifying widths, heights, margins etc: relative and fixed.

Relative

An example of a relative measurement is percentages, which you have used. Percentages are relevant to their containing element. If there is no containing element they are relative to the window.

<div style="width:100%">  <!-- This div will be the full width of the browser, whatever size it is -->     <div style="width:300px">     <!-- this div will be 300px, whatever size the browser is -->         <p style="width:50%">             This paragraph's width will be 50% of it's parent (150px).         </p>     </div> </div> 

Another relative measurement is ems which are relative to font size.

Fixed

An example of a fixed measurement is pixels but a fixed measurement can also be pt (points), cm (centimetres) etc. Fixed (sometimes called absolute) measurements are always the same size. A pixel is always a pixel, a centimetre is always a centimetre.

If you were to use fixed measurements for your sizes the browser size wouldn't affect the layout.
