Hi Longruibin,

Thank you for the review and 5 star rating.

To set homepage to full width just go to Appearance > Customize > Additional CSS and paste below custom CSS code:

.home:not(.page-template-front-page-template) .site-content .content-area {
    -ms-flex: 0 0 100%;
    flex: 0 0 100%;
    max-width: 100%;
}
.home:not(.page-template-front-page-template) .site-content .widget-area {
    display: none;
}

Thank you for using our theme.
