SharePoint 2010 Check Out Green Icon Position Problem

/*

Problem Description:

When I add one document in a list view and check out it. The green icon position is wrong the one page, but it's right in another page which is very strange.

All the css code (coreV4.css) is generated by sharepoint itself.

vs 

The icon's css class is ".ms-vb-icon-overlay". I've searched and searched and searched on internet... But there is no solution for this.

.ms-vb-icon-overlay {
    border: 0 none;
    bottom: -2px;
    left: -7px;
    position: relative;
}

Finally I've asked a collegue who is expert on css. And he pointed the source of problem in 2 minutes while I've spent 1 whole day. 

I've tried to use js code to correct the problem while my js code is always executed before the sharepoint scripts which stop me from correcting it. 

Even though I use "ExecuteOrDelayUntilScriptLoaded" method to try to execute my funtion after all sharepoint scripts execution.

In fact the problem is the  ".ms-vb-icon-overlay" class's parent width is limited to "0.01%" in whatever case. And I just need to modify the parent "width". And my problem is that I've went the wrong direction of the solution before.

And Finally I put the correction css code in my page directly because it won't be executed after sharepoint script if I don't do so.

.ms-vb-icon {padding: 4px 8px 0; vertical-align: top; width: 30px !important;}
