By default in Bootstrap 4, font-size is set to use em or rem for fonts.
What is the best way to adjust the font-size for all viewport sizes? Currently, all elements appear too small.

If you want to customize the default sizing of Bootstrap 4 elements, you can manipulate the font-size unit by setting it in pixels on the HTML element within your own stylesheet. This will override the rem unit used by Bootstrap and apply your desired sizing. To see this in action, check out a codeply project that already has Bootstrap 4 loaded.
Just add these three lines of CSS to your stylesheet:
html {
font-size: 16px;
}
Customize Your Text in Bootstrap 4: There is a variety of classes available for customizing your text:
h1 - h6display-1 - display-4smalllead<!--class="h3" class="display-3", class="small"-->
<div *ngIf="customer_selected" class="h5">
<p>First name: {{selected_customer.first_name}}</p>
<p>Last name: {{selected_customer.last_name}}</p>
</div>
Utilize the predefined .h1 to .h6 classes in bootstrap, or create your own unique CSS class to set font size and apply it to your HTML elements.
Don't forget to include the following as well:
<meta name="viewport" content="width=device-width, user-scalable=no" />
After implementing this change, I noticed a significant improvement in text readability on my mobile browsers.
