Good day.
[Click here to access the test page](http://89.111.180.28/CatalogOfProductsAndServices.php)
Code:
<ul>
<li>
<a href="#">Бытовая техника</a>
<ul>
<li><a href="CatalogOfProductsAndServices.php?id_group=1&id_subgroup=1">Автоаудиоаппаратура</a></li>
...
</ul>
</li>
...
</ul>
Whenever I focus on the link
<a href="#">Бытовая техника</a>
, I notice a point appearing on the first character (refer to screenshots):
1) Screenshot 1
2) Screenshot 2
Could you please explain why the point appears when I focus on the link and how can I remove it?
