table {
    width: 100%;
    height: 100%;
}

td {
    vertical-align: center;
    text-align: center;
}

Using FlexBox

1
<div>Centered content</div>

div {
    display: flex;
    align-items: center;
    justify-content: center;
}

Suggested method which works on Powerapps correctly:

Using translations

1
<div>Centered content</div>

6
div {
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
}

Button Width Fit to The Text

css button width based on char count

as simple as width: fit-content;

If you are developing to a modern browser. https://caniuse.com/#search=fit%20content ³

Troubleshooting CSS

css style not working⁴

i.e. if you put the style below to button in HtmeText control, things below the font-family: "JetBrains Mono",monospace; won’t applied

/* CSS */
.button-30 {
  align-items: center;
  appearance: none;
  background-color: #FCFCFD;
  border-radius: 4px;
  border-width: 0;
  box-shadow: rgba(45, 35, 66, 0.4) 0 2px 4px,rgba(45, 35, 66, 0.3) 0 7px 13px -3px,#D6D6E7 0 -3px 0 inset;
  box-sizing: border-box;
  color: #36395A;
  cursor: pointer;
  display: inline-flex;
  font-family: "JetBrains Mono",monospace;
  height: 48px;
  justify-content: center;
  line-height: 1;
  list-style: none;
  overflow: hidden;
  padding-left: 16px;
  padding-right: 16px;
  position: relative;
  text-align: left;
  text-decoration: none;
  transition: box-shadow .15s,transform .15s;
  user-select: none;
  -webkit-user-select: none;
  touch-action: manipulation;
  white-space: nowrap;
  will-change: box-shadow,transform;
  font-size: 18px;
}

since you need to change " to ' which you need to use Char(20)/Char(34) here instead. change it to font-family: "&Char(20)&"JetBrains Mono"&Char(20)&",monospace;.
