Hi,

1/ If you want to do that, you need to use HTML like this for your widget's title - example:

<a href="https://www.ecoactu.ma/web-tv/">Web tv</a>

With the URL inside href="__" is the URL of your category page.

Check this image for more.

2/ Have you added more this custom CSS code below?

.container.has-banner #logo{ 
    float: left;
} 
.container.has-banner .header-banner{
    float: right;
}

If yes, let's remove it. 

Best Regards,
