I have a class that I want to hide, this is my code:

    /*--------------------------------------------------------------
    Title & Breadcrumb
--------------------------------------------------------------*/
.main-title-section-wrapper {
    clear: both;
    float: left;
    margin: 0;
    padding: 75px 0 90px;
    width: 100%;
}

#header-wrapper .main-title-section-wrapper {
    position: relative;
}

#header-wrapper.header-top-absolute .main-title-section-wrapper {
    position: static;
}


.main-title-section {
    float: left;
    width: 100%;
    margin: 0;
    padding: 0;
    position: relative;
    pointer-events: none;
}



.main-title-section h1 {
    font-size: calc(var(--DTFontSize_H1)/.95);
    margin: 0 0 5px;
    word-break: break-all;
    font-weight: 700;
    text-transform: initial;
    line-height: 1.25em;
    color: #1a1a1a;
}



.breadcrumb {
    clear: both;
    float: left;
    width: 100%;
    margin: 0;
    padding: 0;
    font-size: inherit;
    font-weight: 500;
}

.breadcrumb span:not(.current) {
    display: inline-block;
    margin: 0px 12px;
    padding: 0;
}

.main-title-section-wrapper .breadcrumb-default-delimiter:before {
    content: "";
    background-color: currentColor;
    display: inline-block;
    height: 14px;
    opacity: 0.45;
    position: relative;
    top: -1px;
    vertical-align: middle;
    width: 1px;
    -webkit-transform: rotate(20deg);
    transform: rotate(20deg);
}

.main-title-section h1,
.breadcrumb {
    hyphens: auto;
    word-break: break-word;
    word-wrap: break-word;
    -moz-hyphens: auto;
    -webkit-hyphens: auto;
    -ms-hyphens: auto;
}

.main-title-section-wrapper>.main-title-section-bg,
.main-title-section-wrapper>.main-title-section-bg:after {
    content: "";
    height: 100% !important;
    overflow: hidden;
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    z-index: -1;
    pointer-events: none;
}


/*--------------------------------------------------------------
    Default Colors
--------------------------------------------------------------*/

.breadcrumb {
    color: var(--DTBodyTxtColor);
}

.main-title-section h1 {
    color: var(--DTBlackColor);
}

.breadcrumb a {
    color: var(--DTLinkColor);
    border-bottom: 2px solid transparent;
}

.breadcrumb a:hover {
    border-bottom-color: var(--DTPrimaryColor);
}

.breadcrumb span.current {
    color: var(--DTBodyTxtColor);
}

.main-title-section-wrapper>.main-title-section-bg:after {
    background-color: rgba(var(--DTBlack_RGB), 0.05);
}

.main-title-section-wrapper.dark-bg-breadcrumb>.main-title-section-bg {
    background-color: var(--DTBlackColor);
}

.dark-bg-breadcrumb .main-title-section h1,
.dark-bg-breadcrumb .breadcrumb a,
.dark-bg-breadcrumb .breadcrumb span.current,
.dark-bg-breadcrumb .breadcrumb span:not(.current) {
    color: var(--DTWhiteColor);
}

.breadcrumb a:hover,
.dark-bg-breadcrumb .breadcrumb a:hover {
    color: var(--DTLinkHoverColor);
}



/*--------------------------------------------------------------

/* Primary Color */

.breadcrumb a:hover {
    color: var(--DTPrimaryColor);
}


/*--------------------------------------------------------------

@media only screen and (min-width:1281px) {
    .main-title-section-wrapper {
        padding: 75px 0 90px;
    }
}

@media only screen and (max-width: 1280px) {
    .main-title-section-wrapper {
        padding: 45px 0 50px;
    }
}

/*----*****---- << Mobile (Landscape) >> ----*****----*/


/* Common Styles for the devices below 767px width */

@media only screen and (max-width: 767px) {
    .main-title-section h1 {
        font-size: 28px;
    }
    .main-title-section,
    .main-title-section h1,
    .breadcrumb {
        text-align: center;
    }
}


/* Common Styles for the devices below 479px width */

@media only screen and (max-width: 479px) {
    .main-title-section h1 {
        font-size: 24px;
    }
}

I'm trying to hide main title section wrapper, so far I used this:

    .main-title-section-wrapper {
    display: none ;
    visibility: hidden ;
    }
    
    .main-title-section-wrapper {
       position: absolute;
       top: -9999px;
       left: -9999px; }

And it works on chrome both on desktop that on mobile, but safari on ios still shows that class

What should I do to hide this element also in safari?
