Remove Dash Loading Text

Dash Python
1

Hi there,

Really sorry if this has been answered somewhere or I am not understanding the documentation, I have tried to find an answer somewhere.

I have put my dashboard inside a dcc.Loading component:

    app.layout = dcc.Loading(
    [
        html.Div(
            [
                  <DASHBOARD>
            ])
    ],
    fullscreen=True, type="default"
    )

But the text “Loading…” still appears before the loading spinner, is there a way to remove this text?

Cheers

Ben

When I first looked into this I believe there wasn’t a way to directly change the default “Loading…” it may have changed now, but I have worked around this by using CSS. This places the ‘Loading…’ off the screen but also doesn’t introduce scrollbars.

._dash-loading {
  text-indent: -9999em;
}

For anyone who’d like a complete example of a spinner with CSS on the initial loading screen, I used one of the spinners from here: https://projects.lukehaas.me/css-loaders/

The first part just centers the spinner.

.react-entry-point {
  display: flex;
  justify-content: center;
  align-items: center;
}

._dash-loading {
  color: #006d98;
  font-size: 30px;
  margin: 100px auto;
  width: 1em;
  height: 1em;
  border-radius: 50%;
  position: absolute;
  margin: auto;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  text-indent: -9999em;
  -webkit-animation: load4 1.3s infinite linear;
  animation: load4 1.3s infinite linear;
  -webkit-transform: translateZ(0);
  -ms-transform: translateZ(0);
  transform: translateZ(0);
