Margin-left ignored in Chrome on page-load - html

Question

I have run into following issue. I am displaying a table with data on a page, which is nested in main . Its margin-left isset to 5% (margin-right too) and it has defined width. For some reason when I load the page in Chrome, the left margin is ignored. And here it gets interesting. When I open dev console it gets applied. If I reload the page with console open, it gets broken again. When I turn off any css setting in the console (or basicaly touch anything related to content) it gets fixed again. I am using Unsemantic framework for responsive behavior (only desktop part of it) and I had no trouble with it so far, just this. And since it behaves this strangely, I dont think it has anything to do with the code.
You can see it clearly on this short screencap: http://screencast.com/t/mGotS01iC
Just to be sure, I am posting HTML and CSS for the element:
<table class="grid-90 prefix-5 suffix-5">
<tbody>
<tr>
<th> UserName </th>
<th> Email </th>
<th> Guid </th>
<th> IsUsingTempPasswd </th>
<th> LastLogin </th>
<th> PasswordChanged </th>
<th>Actions</th>
</tr>
<tr>
<td> Administrator </td>
<td> admin#physter.com </td>
<td>
<div class="table-long">00000002-0000-0000-0000-000000000069</div>
</td>
<td class="cell-checkbox">
<input class="check-box" type="checkbox" disabled="disabled">
</td>
<td> </td>
<td> 26.7.2013 12:11:06 </td>

</table>
Here is CSS for the element:
grid-90 {
float: left;
width: 90%;
}
.suffix-5 {
margin-right: 5%;
}
.prefix-5 {
margin-left: 5%;
}
.grid-5, .mobile-grid-5, .tablet-grid-5, .grid-10, .mobile-grid-10, .tablet-grid-10, .grid-15, .mobile-grid-15, .tablet-grid-15, .grid-20, .mobile-grid-20, .tablet-grid-20, .grid-25, .mobile-grid-25, .tablet-grid-25, .grid-30, .mobile-grid-30, .tablet-grid-30, .grid-35, .mobile-grid-35, .tablet-grid-35, .grid-40, .mobile-grid-40, .tablet-grid-40, .grid-45, .mobile-grid-45, .tablet-grid-45, .grid-50, .mobile-grid-50, .tablet-grid-50, .grid-55, .mobile-grid-55, .tablet-grid-55, .grid-60, .mobile-grid-60, .tablet-grid-60, .grid-65, .mobile-grid-65, .tablet-grid-65, .grid-70, .mobile-grid-70, .tablet-grid-70, .grid-75, .mobile-grid-75, .tablet-grid-75, .grid-80, .mobile-grid-80, .tablet-grid-80, .grid-85, .mobile-grid-85, .tablet-grid-85, .grid-90, .mobile-grid-90, .tablet-grid-90, .grid-95, .mobile-grid-95, .tablet-grid-95, .grid-100, .mobile-grid-100, .tablet-grid-100, .grid-33, .mobile-grid-33, .tablet-grid-33, .grid-66, .mobile-grid-66, .tablet-grid-66 {
-moz-box-sizing: border-box;
padding-left: 10px;
padding-right: 10px;
}
table {
border: medium none;
margin-bottom: 2.5em;
margin-top: 1em;
text-align: left;
width: 100%;
}
body {
color: #006666;
font-family: "Segoe UI",Verdana,Helvetica,Sans-Serif;
font-size: 0.85em;
}
Anybody has an idea? I would be grateful for solution that would allow me keep the framework as it is and do not overwrite its behavior...

Answer 1

Width of 90% and the fact that you want the table on center are enough. The edges will be calculated automatically. So your code would look like this:
CSS
grid-90 {
width: 90%; }
.grid-5, .mobile-grid-5, .tablet-grid-5, .grid-10, .mobile-grid-10, .tablet-grid-10, .grid-15, .mobile-grid-15, .tablet-grid-15, .grid-20, .mobile-grid-20, .tablet-grid-20, .grid-25, .mobile-grid-25, .tablet-grid-25, .grid-30, .mobile-grid-30, .tablet-grid-30, .grid-35, .mobile-grid-35, .tablet-grid-35, .grid-40, .mobile-grid-40, .tablet-grid-40, .grid-45, .mobile-grid-45, .tablet-grid-45, .grid-50, .mobile-grid-50, .tablet-grid-50, .grid-55, .mobile-grid-55, .tablet-grid-55, .grid-60, .mobile-grid-60, .tablet-grid-60, .grid-65, .mobile-grid-65, .tablet-grid-65, .grid-70, .mobile-grid-70, .tablet-grid-70, .grid-75, .mobile-grid-75, .tablet-grid-75, .grid-80, .mobile-grid-80, .tablet-grid-80, .grid-85, .mobile-grid-85, .tablet-grid-85, .grid-90, .mobile-grid-90, .tablet-grid-90, .grid-95, .mobile-grid-95, .tablet-grid-95, .grid-100, .mobile-grid-100, .tablet-grid-100, .grid-33, .mobile-grid-33, .tablet-grid-33, .grid-66, .mobile-grid-66, .tablet-grid-66 {
-moz-box-sizing: border-box;
padding-left: 10px;
padding-right: 10px;
}
table {
border: medium none;
margin-bottom: 2.5em;
margin-top: 1em;
text-align: left;
margin: 0 auto;
}
body {
color: #006666;
font-family: "Segoe UI",Verdana,Helvetica,Sans-Serif;
font-size: 0.85em;
}
In HTML remove the names of the two divisions: <table class="grid-90"> I hope that helps!

Answer 2

Only thing needed was a little "hack" - adding float:none !important; to <table> elelemnt was enough.
Thanks to Dragos Sandu who put me up to this - removing float:left from grid-90 class was his idea and first step I tried.
