Hi Phuong,

If you are trying to remove the gray border and footer that are currently now in your home page then Go to Appearance -> Theme Options -> Design Options Tab -> Custom CSS paste the following CSS code and Click on save all changes button:

.wrapper {
    -webkit-box-shadow: none;
    -moz-box-shadow: none;
    box-shadow: none;
}
#colophon {
    display: none;
}

Thank you!
