Hi,
1.
Please refer this post https://seatheme.net/forums/topic/how-to-install-font-physical-copy/#post-14836
Because Arial is default system font, so you can only use the CSS into “Appearance > Customize : Additional CSS”:
/* Heading font */
body.single .title-wrap-tit,.title-wrap-h1, .archive-grid-item-tit,.title-wrap-meta-a,.archive-grid-item-meta-item,h1,h2,h3,h4,h5,h6 {font-family: arial, helvetica, sans-serif;}
/* Body text */
body,.single-portfolio-fullscreen-slider .owl-dot.active{font-family: arial, helvetica, sans-serif;}
2.
I found there is unnecessary html div outer :
<div style="padding:71.86% 0 0 0;position:relative;">

It cause the issue. Please try to remove it, maybe it is from some plugin.
If you can not remove the div, please use the CSS into “Appearance > Customize : Additional CSS”:
.videoWrapper.video-wrap.video-post-wrap {padding-top: 0 !important;}
Regards!
