[SOLVED] page centering issues

VanderBOOM · #1 Nov 29th, 2007, 09:15

Can anyone explain the following:

On my indexpage I run a slideshow using javascript.

I have centered my page using:

<body LEFTMARGIN=0 TOPMARGIN=0 onLoad="runSlideShow()">
<table width="100%" height="100%" border="0" cellpadding="0" cellspacing="0">
.....rest of code

so far so good, but when I switch to another page without javascript also centering using the code:

Code: Select all

<body LEFTMARGIN=0 TOPMARGIN=0>
<table width="100%" height="100%" border="0" cellpadding="0" cellspacing="0">
.....rest of code

a shift occurs of 5 pixels to the left, and 8 pixels to the top. I can prevent this by just putting a <script></script> in the header of the other page. But I would like to understand why this happens.

Your code is invalid, with 24 HTML errors. Fix them first, then see whether you still have the problem.

Note also that this is a bad method for centring your site and controlling margins. Use CSS instead.

Use CSS to center you site - How do I center my site horizontally?

I will buy a CSS bible, to see whether I can solve the problem. I need to center my page in both directions (not only horizontally). I found out that the (bad) way I'm using, gives me the results I want, except for this strange javascript behaviour.

How to centre horizontally and vertically?

VanderBOOM · #6 Dec 3rd, 2007, 14:18

Since I'm not very into CSS (haven't received my bible yet

),
I've come up with this code in the header

Code: Select all

<style type="text/css" media="screen">
<!--
/* commented backslash hack for ie5mac \*/ 
html, body{height:100%;} 
html,body {margin:0;padding:0;}
/* end hack */
#verticaal{
 position:absolute;
 top:50%;
 margin-top:-282px;/* half height*/
 width:100%;
}
#horizontaal {
 position:absolute;
 left:50%;
 margin-left:-400px;/* half width*/
 height:100%;
}
-->
</style>

:

and used

Code: Select all

<div id="verticaal"> 
<div id="horizontaal">
pageitems to center
in my case a table....
</div>
</div>

I hope this is the correct way to center my page in both directions ?
If so, thanks for pointing me in the right direction !

My god, what hideous code!

All you need is { margin: 0 auto; }.

Just grapped the code from the examples Karinne was pointing me to.....

I ordered my CSS bible, so within no time I will understand more about the mountains and pitfalls of it.

My mistake: you're centring vertically as well (what a weird thing to do). {margin: 0 auto } will not suffice.

Moving to CSS forum

VanderBOOM · #11 Dec 4th, 2007, 14:55

I thought you where aiming at

Code: Select all

html, body{height:100%;} 
html,body {margin:0;padding:0;}

because I already found out that what you proposed only sets the starting position to the left uppercorner.

I love to make centered pages

it's a kind of house-style, and they sell very well ! My problems started when I used javascript to make a slide show on one page......

But everything works fine now

So.. The problem is solved?

VanderBOOM · #13 Dec 4th, 2007, 15:06

Yes it is. CSS did the trick, although I haven't figured out what the real problem was using the (wrong)centering way as earlier discribed. Another good thing is that centering with CSS gives good results in IE7 when the zoom function is used.
