So just change you child theme css and it should work.

I make description visible and little bit smaller so it will fit in.
display: block – this element you don’t need there.

.site-description {
font-size: 1.3rem;
}

From this element you can take out this
.site-title {
display: inline-block;
float: left;
}

.site-branding {
display: inline-block;
}

.header-wrapper {
display: block;
width: 49%;
}

Hope it will help.

Hi

If you use specific fullwidth.php template for your page and you have taken widget sidebar out of your template code, it shouldn’t appear on that page.
