HI @Zakariatheguy
You can try follow this path:
Themes => edit code => asset => base.css
and add this code to bottom of the file base.css

.announcement-bar {
 height: 50px;	
 overflow: hidden;
 position: relative;
}
.announcement-bar p{
 position: absolute;
 width: 100%;
 height: 100%;
 margin: 0;
 text-align: center;
 -moz-transform:translateX(100%);
 -webkit-transform:translateX(100%);	
 transform:translateX(100%);
 -moz-animation: marquee 15s linear infinite;
 -webkit-animation: marquee 15s linear infinite;
 animation: marquee 15s linear infinite;
}

@-moz-keyframes marquee {
 0%   { -moz-transform: translateX(100%); }
 100% { -moz-transform: translateX(-100%); }
}
@-webkit-keyframes marquee {
 0%   { -webkit-transform: translateX(100%); }
 100% { -webkit-transform: translateX(-100%); }
}
@keyframes marquee {
 0%   { 
 -moz-transform: translateX(100%); /* Firefox bug fix */
 -webkit-transform: translateX(100%); /* Firefox bug fix */
 transform: translateX(100%); 		
 }
 100% { 
 -moz-transform: translateX(-100%); /* Firefox bug fix */
