XF 2.2 Share icons are vertically displayed

[Nicolas FR]

Hello,

I would like to display shareicons instead 'create a new thread' button in forum home.
This is how i customize forum_overview_wrapper template

<xf:ad position="forum_overview_top" />
<xf:widgetpos id="forum_overview_top" />

<xf:pageaction>
    <xf:widget key="forum_overview_share_page" />
</xf:pageaction>

{$innerContent|raw}

<xf:ad position="forum_overview_bottom" />
<xf:widgetpos id="forum_overview_bottom" />

And this is how the widget is displayed, vertically !

(i make some changes in extra.less too)

[data-widget-key="forum_overview_share_page"] {
    .block-minorHeader {display: none;}
    .block-body {background: @xf-pageBg;}
    .block-container {border: none}
}

How to get icons displayed horizontally ?
Thanks !
