You can adjust the padding for that widget area on line 1977 (it’s in your style.css file)
.header-image .site-header .widget-area {
padding: 1.9px 0;
padding: 2.5rem 0;
}
Just remove the padding: 2.5rem 0;
line entirely, and adjust the line above it. At the moment you have it as 1.9px and it should be something different. I would change it to around 25px and start with that and adjust if you need. Here is an example –
.header-image .site-header .widget-area {
padding: 25px 0;
}
