在絕對位置上居中文本

Question

我正在制作團隊花名冊頁面。 我受到https://www.fcbarcelona.com/en/football/first-team/players的啟發，並嘗試盡可能多地復制它，進行一些練習。我遇到的問題是，讓他們的姓氏在背景中可見，我正在使用position:absolute和paddign-top將其放置在我想要的位置，但我似乎無法管理，以找到將姓氏放在 div 的確切中心的正確方法

 const player = Array.from(document.getElementsByClassName('player')); const lastname_background = Array.from(document.getElementsByClassName('lastname-background')); const info = Array.from(document.getElementsByClassName('info')); const hidden_stats = Array.from(document.getElementsByClassName('hidden-stats')); player.forEach(i=>i.addEventListener('mouseover',()=>{ const index = player.indexOf(i) lastname_background[index].style.paddingTop = "25vh"; info[index].style.paddingTop = "31vh"; lastname_background[index].style.transition = "0.4s"; info[index].style.transition = "0.4s"; hidden_stats[index].style.visibility = "visible"; hidden_stats[index].style.transition = "1s"; })) player.forEach(i=>i.addEventListener('mouseout',()=>{ const index = player.indexOf(i) lastname_background[index].style.paddingTop = "33vh"; info[index].style.paddingTop = "40vh"; lastname_background[index].style.transition = "0.4s"; info[index].style.transition = "0.4s"; hidden_stats[index].style.visibility = "hidden"; }))

Answer 1

添加position: relative; 到.player使其成為絕對定位子元素的引用。
