In fact, I add this code :target

/* Apply styles to the targeted section */
:target {
    margin-top: 50px; 
    padding-top: 20px;
    animation: highlight 1s ease;  
    transform: translateX(20px);  
    scroll-margin-top: 50px; /* This ensures the section is not hidden under a fixed header */
}

/* Define the highlight animation */
@keyframes highlight {
    from { background-color: yellow; }
    to { background-color: transparent; }
}

the objective is to translate to the section of the id with top-margin and highlight the <h2>
