实现-卡中的按钮不会居中
[英]Materialize - Button in Card won't go center
问题描述
I have a card in which there is button (Start button) which won't go to the center of the card. 
我有一张卡片，里面有个按钮（“开始”按钮），不会转到卡片的中央。
I tried center-align class, but that won't do it. 我尝试了center-align类，但是那没有做。 I also tried using my id and class and trying text-align: center; 我也尝试使用我的id和class并尝试text-align: center; in my css. 在我的CSS中。 But that did not work either. 但这也不起作用。
Don't know what I'm missing. 不知道我在想什么。
Here is what I have: 这是我所拥有的：

You have to use the center-align class on a parent element of the button, so I added a parent with class="center-align" 您必须在按钮的父元素上使用center-align类，所以我添加了class="center-align"的父对象
body { display: flex; min-height: 100vh; flex-direction: column; background-color: rgb(232, 232, 232); } main { flex: 1 0 auto; } .tabs .tab a { color: #00ACC1; } .tabs .tab a:hover, .tabs .tab a.active { background-color: transparent; color: #00ACC1; } .tabs .tab.disabled a, .tabs .tab.disabled a:hover { color: rgba(102, 147, 153, 0.7); } .tabs .indicator { background-color: #00ACC1; } .naslovPrijava { font-size: 20px !important; text-align: center; height: 18px; } .naslovUcesnik { font-size: 18px !important; text-align: left; margin-left: -15px; margin-top: -15px; } .pomeriKarticu { margin-left: -35px; height: 50px; } .dugmeStart { text-align: center; }

You can use margin to achieve this also 您也可以使用保证金来实现这一目标
.dugmeStart {
text-align: center;
display: block;/**Added This**/
margin: 0 auto; /**Added This**/
}
