Hanya apabila saya mengalih keluar pautan saya dapat melihat tag div dengan petua alat. Bagaimanakah hubungan keduanya? Kandungan div tidak muncul dengan pautan.
.tooltip {
position: relative;
display: inline-block;
border-bottom: 1px dotted black;
}
.tooltip .tooltiptext {
visibility: hidden;
width: 120px;
background-color: black;
color: #fff;
border-radius: 6px;
}
.tooltip:hover .tooltiptext {
visibility: visible;
}
div#tdemo1 {
animation-name: animate;
animation-duration: 3s;
width: 100px;
height: 100px;
background-color: red;
}
@keyframes animate {
0% {
background-color: red;
}
33% {
background-color: yellow;
}
66% {
background-color: blue;
}
99% {
background-color: white;
}
}

Saya cuba menggunakan petua alat dengan tag div dan menggunakan bootstrap untuk menunjukkan butang. Hanya satu daripadanya kelihatan betul pada satu masa.

Anda perlu menukar elemen
.tooltip元素的类，因为bootstrap将其识别为bootstrapdan mengatasi nilainya sendiri di dalamnya..tooltipp { position: relative; display: inline-block; border-bottom: 1px dotted black; } .tooltipp .tooltiptext { visibility: hidden; width: 120px; background-color: black; color: #fff; border-radius: 6px; } .tooltipp:hover .tooltiptext { visibility: visible; } div#tdemo1 { animation-name: animate; animation-duration: 3s; width: 100px; height: 100px; background-color: red; } @keyframes animate { 0% { background-color: red; } 33% { background-color: yellow; } 66% { background-color: blue; } 99% { background-color: white; } }<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@4.6.2/dist/css/bootstrap.min.css"> <body style="background-image:linear-gradient(180deg,blue,violet);"> <div id="tdemo1" class="tooltipp">Hover over me <span class="tooltiptext">Tooltip text</span> </div> <div id="bdemo1" class="container"> <h1>types of buttons in bootstrap:</h1> <button type="button" class="btn btn-outline-primary">Primary</button> <button type="button" class="btn btn-outline-secondary">Secondary</button> <button type="button" class="btn btn-outline-success">Success</button> <button type="button" class="btn btn-outline-info">Info</button> <button type="button" class="btn btn-outline-warning">Warning</button> <button type="button" class="btn btn-outline-danger">Danger</button> <button type="button" class="btn btn-outline-dark">Dark</button> <button type="button" class="btn btn-outline-light text-dark">Light</button> </div>
