The easiest way to avoid showing invisible text while custom fonts load is to temporarily show a system font. By including font-display: swap in your @font-face style.

2. What is @font-face?

A @font-face is a simple CSS rule through which you can apply a custom font to a text. It has extensions like woff2, woff, ttf, etc.
For example, a @font-face code will look like this-
You can easily fix this issue

Css Property:- font-display: swap;

Before

@font-face {
font-family: 'Pacifico';
font-style: normal;
font-weight: 400;
src: local('Pacifico Regular'),local('Pacifico-Regular'),
url(https://fonts.gstatic.com/s/pacifico/v12/FwZY7-Qmy14u9lezJ-6H
6MmBp0u-.woff2) format('woff2');
}

After

@font-face {
font-family: 'Pacifico';
font-style: normal;
font-weight: 400;
src: local('Pacifico Regular'),local('Pacifico-Regular'),
url(https://fonts.gstatic.com/s/pacifico/v12/FwZY7-Qmy14u9lezJ-6H 6MmBp0u-.woff2)
format('woff2');
Font-display: swap;
}

3. Google Fonts

Google Fonts won’t add font-display: swap; rule to their font, but now they support a new query parameter to apply the font-display: swap; by adding the &display=swap parameter at the end of the google font file.
