Hello Ahmed!
Use next CSS codes to avoid the Search-box intersection issue:
@media only screen and (max-width: 992px) {
#vision-search-box input[type=text]{
width: 240px!important;}
}
@media only screen and (min-width: 993px) {
#vision-search-box input[type=text]{
width: 640px!important;}
}
2.
First, go to the Customizing->General->Pages menu, and change the “Pages background color” per your wish.

then, insert the next code to set the Article background color to the white:
.article-wrapper {
background-color: #FFF;
}
