After the Divi 3.0.50 update, you may notice the backgrounds for the CTA's on the homepage have been resized like this:

To rectify this issue locate the following section of CSS in the Fleur stylesheet:

.ds-home-cta .et_pb_promo_description:before {
    position: absolute;
    content: '';
    width: calc(100% - 60px);
    height: calc(100% - 60px);
    top: 0;
    left: 0;
    margin: 30px;
    background: #ffffff;
    border: 3px double #fee1e1;
    opacity: .8;
    z-index: 1;
}

And remove the .et_bp_promo_description class so that the CSS then looks like this:

.ds-home-cta:before {
    position: absolute;
    content: '';
    width: calc(100% - 60px);
    height: calc(100% - 60px);
    top: 0;
    left: 0;
    margin: 30px;
    background: #ffffff;
    border: 3px double #fee1e1;
    opacity: .8;
    z-index: 1;
}

Fleur version 1.2 incorporates this update.
