Elements normally attach (get a renderer) during style-resolve, which is a precursor to layout.

An element normally has a renderer, but elements can explicitly opt out (by being display: none) or a few other reasons:

bool NodeRenderingContext::shouldCreateRenderer() const
{
    if (!m_node->document()->shouldCreateRenderers())
        return false;
    if (!m_parentDetails.node())
        return false;
    RenderObject* parentRenderer = this->parentRenderer();
    if (!parentRenderer)
        return false;
    if (!parentRenderer->canHaveChildren())
        return false;
    if (!m_parentDetails.node()->childShouldCreateRenderer(*this))
        return false;
    return true;
}
