Saya mempunyai blok yang mengandungi kandungan yang dipaparkan pada tuding. Cara kesannya adalah:
.hoverCard
Kandungan asas dipaparkan secara lalai (kandungan dalam .hoverCard__showOnHover disembunyikan)
Pengguna menuding ke atas .hoverCard, yang .hoverCard__showOnHover
显示其内容,并且 .hoverCard__body
beralih ke atas (memberi kesan "terbuka") Masalah yang saya hadapi ialah:
visibility:hidden
、opacity:0
和 height:0
仍然为 .hoverCard__showOnHover
保留空间。这意味着,如果默认情况下,.hoverCard__body
的底部填充量为 40px,而 .hoverCard__showOnHover
dengan ketinggian 100px menghilangkan keperluan untuk pengguna melayang di atas .hoverCard untuk melihat ruang 140pxGSAP
逐渐赋予 .hoverCard__showOnHover
ketinggian. Tetapi tiada nasib kerana ia masih mempunyai masalah di atas Adakah cara untuk menyelesaikan masalah ini? Tidak semestinya menggunakan GSAP, saya hanya mencuba GSAP untuk cuba menyelesaikan masalah di atas.
const hoverCard = document.querySelector('.hoverCard'); const hoverCardBodyShowOnHover = document.querySelector('.hoverCard__showOnHover'); hoverCard.addEventListener('mouseenter', function() { gsap.to(hoverCardBodyShowOnHover, { duration: 0.5, display: 'block', height: 'auto', ease: 'power4.out' }); }); hoverCard.addEventListener('mouseleave', function() { gsap.to(hoverCardBodyShowOnHover, { duration: 0.5, height: 0, ease: 'power4.out', onComplete: function() { this.targets()[0].style.display = 'none'; }}); });

Begini rupa versi lalai kad secara visual (kad kanan) dan cara interaksi tuding berfungsi (kad kiri):
Perhatikan bahawa ketinggian kad tidak meningkat. Sebaliknya, badan bergerak ke atas (dalam kad) untuk mendedahkan kandungan.
Berdasarkan jawapan Kooilnc:
:root { --black: #000000; --white: #ffffff; --yellow: #FFE775; } /* general */ body { background-color: var(--white); color: var(--black); } section { margin: 100px 0 300px 0; } /* card */ .hoverCard { margin-bottom: 15px; width: 100%; border-radius: 8px; overflow: hidden; background-color: var(--black); color: var(--white); border: 1px solid var(--black); position: relative; /* added */ } .hoverCard * { transition: all 0.5s ease; } .hoverCard:hover .hoverCard__body { transform: translateY(-75px); } .hoverCard:hover .hoverCard__body .hoverCard__showOnHover { /* opacity: 1; visibility: visible; display: block; height: */ auto; overflow: initial; /* added */ height: auto; /* added */ max-height: 100px; /* added */ transform: translateY(75px); } .hoverCard__header { height: 200px; background-color: var(--yellow); } .hoverCard__showOnHover { overflow: hidden; max-height: 0; /* added */ transition: max-height 0.5s ease-in-out; /* added */ overflow: hidden; /* added */ } .hoverCard__body { width: 100%; padding: 30px 30px 40px 30px; }

Selain itu, adakah kita perlu menentukan nombor untuk max-height: 100px;
? Bagaimana jika saiz kandungan tidak diketahui dan perlu dinamik?
Kaedah terkini:
:root{ --white: #FFFFFF; --black: #000000; --yellow: #FFE775; } section{ padding: 150px 0; } .hoverCard { margin-bottom: 15px; width: 100%; border-radius: 8px; overflow: hidden; padding-bottom: 180px; // seems I need this to maintain height background-color: var(--black); color: var(--white); border: 1px solid var(--black); /* only on non touch devices ================================== */ @media (hover: hover) { * { transition: all 0.5s ease; } &:hover { .hoverCard__body { transform: translateY(-75px); } .hoverCard__showOnHover { display: block; max-height: none; overflow: visible; } } } &__showOnHover { display: none; max-height: 0; overflow: hidden; transition: max-height 0.5s ease-in-out; } /* only on touch devices ================================== */ @media (pointer: coarse) { &__showOnHover { margin-bottom: 30px; } } /* =============================== */ &__header { height: 350px; background-color: var(--yellow); } &__body { position: absolute; bottom: 0; width: 100%; padding: 30px 30px 0px 30px; color: var(--white); background-color: var(--black); &-text { margin-bottom: 60px; } } }

Oleh yang di atas:
.hoverCard__body
上方出现不必要的空格(应仅填充顶部 30px
). P粉7606754522024-03-28 11:47:55
Caranya ialah dengan menetapkan teks untuk dipaparkan kepada max-height: 0
和 overflow: hide
. Ini ialah contoh minima boleh diulang.
body { margin: 1rem; font-family: system-ui, sans-serif; } .item { position: relative; overflow: hidden; margin-right: 0.8rem; width: 150px; float: left; border: 1px solid #777; border-radius: 3px; } .item.first { background: url("https://upload.wikimedia.org/wikipedia/commons/d/d0/Queen_Clementia_of_Hungary.jpg") no-repeat top left; background-size: cover; height: 150px; } .collapsible { height: inherit; width: inherit; position: absolute; bottom: 0; } .collapsible .header { background-color: #EEE; color: #000; text-align: center; font-weight: bold; font-size: 0.9rem; cursor: pointer; bottom: 0; width: 100%; position: absolute; opacity: 0.8; } .item .collapsible .collapsibleTxt { max-height: 0; text-align: left; font-size: initial; color: #444; overflow: hidden; padding: 4px; font-weight: normal; transition: max-height 0.5s ease-in-out; } .header:hover .collapsibleTxt { overflow: initial; height: auto; max-height: 100px; }
Who's that?It's Clementia of Hungary!
