After check again on your second issue, it seems like that is another part issue coming from your ads :
<div style="float:right">
<script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<!-- مستطيل المدونة -->
<ins class="adsbygoogle"
style="display:inline-block;width:160px;height:600px"
data-ad-client="ca-pub-5513800218382393"
data-ad-slot="5300209518"></ins>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});
</script>
</div>
Because you have specific the width and height for your ads causing it not display nicely on the page, I would suggest you to switch to use Google responsive ads code, so it should display nicely.
