slideshow

Please I wold ask you why I have a white space right image
thank you

It due to the width of the image in slideshow, it has width of 1300px while the space is larger so there is a gap there.

You can use this custom CSS to make the image displays fully:

@media (min-width: 1200px) {
.slideshow .img-bg img {
    width: 100%;
}
}
