Using taliwind css to change the default font?

Hello，
I know I can use the class name to change the editor style

.w-md-editor-text-pre > code,
.w-md-editor-text-input {
  font-size: 23px !important;
  line-height: 24px !important;
}

I want to use taliwind css to change the default editor font style,
However, the added font-family seems like does not work (replace by the default font-family)

.my-taliwind-css-family {
    font-family: some style
}

replace by

.wmde-markdown {
    -webkit-text-size-adjust: 100%;
    font-family: -apple-system, 'Segoe UI', Helvetica, Arial, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji';
    font-size: 16px;
    line-height: 1.5;
    word-wrap: break-word;
    color: var(--color-fg-default);
    background-color: var(--color-canvas-default);
}

Is there any good solution to deal with this?

Start by inspecting the editor selectors .w-md-editor-text-pre > code, .w-md-editor-text-input, and .wmde-markdown shown in the report, then check which rule controls the rendered font family. Confirm the change by applying the requested font style and verifying that the editor text no longer uses the default family.
