No, I have not. So what you saw was probably an svg image, but I cannot see it. Did you hide it somehow?

If you can see it, try to identify the element that hides a part of the image. Is it the menu?

Did you replace any fontawesome files in the fonts folder? It seems that it tries to replace the original icon fonts by svg.

Did you modify the theme code, or install any plugin? Unpublish your newly installed plugins, and check the site!

I cannot see the band on my phone.

Which is the main image?

I suggest to use the developer tool in Chrome or Firefox to investigate the css.

Try this with the background image, we remove it from other pages:

body:not(.home) {background-image: none;}

Try it as a background image of that page!
Or if you just wanted it closer to the menu:

body.home #content {padding-top: 0;}

Html elements can have css classes:

<h1 class=”scrollflow -slide-top -opacity”>Slide-Top with opacity fading</h1>
<p class=”scrollflow -pop -opacity”>Pop-Effect</p>

If you want to apply it to a full widget, I suggest to use the Widget CSS Classes plugin.

To sum up, if you need a scroll effect on an element, add the scrollflow css class and at least one of the following CSS classes to the desired object: -slide-top, -slide-left, -slide-right, -slide-bottom, -pop, -opacity.

I suggest to search for a one page theme. This is not like that.

Copy the index.php and single.php into the child theme.
Rename the index.php to home.php, modify the class of the primary div, and remove the get_sidebar.
The class can be copied from the page-full-width.php.
The same modifications must be made in the single.php

In this theme it requires php coding in a child theme, you need a home.php and a modified single.php, but such customization is not part of the support of the free themes. In the pro version you can choose the full width layout as the default, and then set an other layout for every page in the editor.

In the theme customizer:
Header layout/Display search form: No

The free version has only left-sidebar layout.
