1. The code is not exactly the same. They have different number of lines.

2. It works on landscape mode actually.

3. Your code contains errors as I mentiond from the very beginning. I have removed all the code except a few lines to be sure to remove all the broken part. Now check how it works.

I post your original code here so you can restore it

for landscape

.search-button-icon {
	color:#FFF;
}
.mobile-nav .searchform input[type=text] {
    border-bottom: 1px solid #fff32a;
    background: #252525 !important;
		text-transform: uppercase;
}
.whb-header-bottom-inner {
    height: 70px;
}
.page-title {
    padding: 50px 0;
}
.title-line-one .product-grid-item.col-6 .product-title, .title-line-two .product-grid-item.col-6 .product-title {
    line-height: inherit;
}
.whb-header-bottom {
    height: 70px;
}
.product-grid-item .woodmart-buttons {
    background-color: #dededeb3;
}

		color: white;
}

    background-color: #2b2b2b;
