Bulma progress text in middle

问题

Why when I use progress from Bulma CSS framework (https://bulma.io/documentation/elements/progress/)

and I put text between tags, I don't see any value.

<progress class="progress is-danger" value="90" max="100">90%</progress>

How add text on middle on progress in Bulma?

回答1:

It's normal that you don't see the value

<progress value="90" max="100">90%</progress>

There is no built-in solution.

But according to show-a-progress-bars-value-number-like-55-on-the-bar-by-using-css the following is a solution

progress.show-value {
  position: relative;
}

progress.show-value:after {
  content: attr(value)'%';
  position: absolute;
  top: 0;
  left: 50%;
  -webkit-transform: translateX(-50%);
  -ms-transform: translateX(-50%);
  transform: translateX(-50%);
  font-size: calc(1rem / 1.5);
  line-height: 1rem;
}

progress.show-value.is-small:after {
  font-size: calc(0.75rem / 1.5);
  line-height: 0.75rem;
}

progress.show-value.is-medium:after {
  font-size: calc(1.25rem / 1.5);
  line-height: 1.25rem;
}

progress.show-value.is-large:after {
  font-size: calc(1.5rem / 1.5);
  line-height: 1.5rem;
}

<progress class="progress is-danger is-small show-value" value="90" max="100">90%</progress>
<progress class="progress is-danger show-value" value="90" max="100">90%</progress>
<progress class="progress is-danger is-medium show-value" value="90" max="100">90%</progress>
<progress class="progress is-danger is-large show-value" value="90" max="100">90%</progress>

UPDATE

The solution above does not work on Firefox!

Here is an overall solution:

.progress-wrapper {
  position: relative;
}

.progress-value {
  position: absolute;
  top: 0;
  left: 50%;
  transform: translateX(-50%);
  font-size: calc(1rem / 1.5);
  line-height: 1rem;
  font-weight: bold;
}

.progress.is-small+.progress-value {
  font-size: calc(0.75rem / 1.5);
  line-height: 0.75rem;
}

.progress.is-medium+.progress-value {
  font-size: calc(1.25rem / 1.5);
  line-height: 1.25rem;
}

.progress.is-large+.progress-value {
  font-size: calc(1.5rem / 1.5);
  line-height: 1.5rem;
}

<div class="progress-wrapper">
  <progress class="progress is-danger is-small" value="90" max="100">90%</progress>
  <p class="progress-value has-text-white">90%</p>
</div>
<div class="progress-wrapper">
  <progress class="progress is-danger" value="90" max="100">90%</progress>
  <p class="progress-value has-text-white">90%</p>
</div>
<div class="progress-wrapper">
  <progress class="progress is-danger is-medium" value="90" max="100">90%</progress>
  <p class="progress-value has-text-white">90%</p>
</div>
<div class="progress-wrapper">
  <progress class="progress is-danger is-large" value="90" max="100">90%</progress>
  <p class="progress-value has-text-white">90%</p>
</div>
