Question

Field

input[type="number"]does not display placeholder text in the latest firefox for a particular font family, for example font-family: 'Open Sans';. Current Version of Firefox Quantum 57.0.2 (64-bit)

Answer 3

For some reason, when I go to the height of your input field something above 40 pixels, it seems to work. Try the following:

input {
    display: block;
    box-sizing: border-box;
    width: 100%;
    height: 41px;
    padding: 0 10px;
    line-height: 40px;
    background: #fafafa;
    border: 1px solid tomato;
    padding: .5rem 1rem;
    font-family: 'Open Sans';

    background-clip:content-box;
    background-color: deepskyblue;
}

I do not understand why this corrects this.

EDIT

You use PADDING twice in your css input declaration ...

Just delete the first one: padding: 0 10px;

And save: padding: .5rem 1rem;

body{
  padding: 2rem;
}
input {
    display: block;
    box-sizing: border-box;
    width: 100%;
    height: 40px;
    line-height: 40px;
    background: #fafafa;
    border: 1px solid tomato;
    padding: .5rem 1rem;
    font-family: 'Open Sans';
    background-clip:content-box;
    background-color: deepskyblue;
}

input[type="number"] {
    
    // line-height: 1.5;
}

<input type="text" placeholder="Text field" />
<hr>
<input type="number" placeholder="Number field" />
