Hi Youness tallih,
You can edit the layout file in your template.
Example: main-right.xml file.
Please open it in "your_site/templates/smart_news25/layouts", finding:
<header order="2" id="yt_header">
<positions>
<position width="500px" height="" type="feature">@logo</position>
<position width="" height="" type="modules">header1</position>
<position width="210px" type="modules">header2</position>
</positions>
</header>
change to
<header order="2" id="yt_header">
<positions>
<position width="270px" height="" type="feature">@logo</position>
<position width="730px" height="" type="modules">header3</position>
<position width="" height="" type="modules">header1</position>
<position width="210px" type="modules">header2</position>
</positions>
</header>
Thanks
