Bug 95772 – CSS 2.1 failure: floats-149 fails

• Component: CSS
• Status: RESOLVED FIXED

[Robert Hogan]

Should the RenderInline expand to enclose the float? It currently gets a zero height - which is why the RenderBlock parent gets a zero height.

[Dave Hyatt]

Just a guess but:


static bool alwaysRequiresLineBox(RenderInline* flow)
{
    // FIXME: Right now, we only allow line boxes for inlines that are truly empty.
    // We need to fix this, though, because at the very least, inlines containing only
    // ignorable whitespace should should also have line boxes.
    return !flow->firstChild() && flow->hasInlineDirectionBordersPaddingOrMargin();
}


I think !flow->firstChild() (the subject of the FIXME) is probably why we're failing this test.

You should replace that with a function that recurs and looks for whether or not you have child content that will force the creation of a line box.

[Robert Hogan]

This test can be at least partly reduced to the fact that the inline div will get a line box in this case:

  <div><div style="display:inline"></div></div>

But not in this:

  <div><div style="display:inline"><span></span></div></div>

FF, Opera and IE create a line box for the latter case. So presumably WebKit should too. But then WebKit would always create a line box for empty lines. Is that what should happen?
