Tipografía
Usa el componente de tipografía para mantener tus contenidos y diseño tan limpio y eficiente como sea posible.
Too many type sizes and styles at once can spoil any layout. A typographic scale has a limited set of type sizes that work well together along with the layout grid.
General
The Roboto font will not be automatically loaded by Material-UI. You are responsible for loading any fonts used in your application. Roboto tiene algunas maneras fáciles de empezar. For more advanced configuration, check out the theme customization section.
Roboto Font CDN
Shown below is a sample link markup used to load the Roboto font from a CDN:
<link rel="stylesheet" href="https://fonts.googleapis.com/css?family=Roboto:300,400,500,700&display=swap" />
Instalar con npm
Puede instalarlo escribiendo el siguiente comando en su terminal:
npm install @fontsource/roboto
Entonces, puede importarlo en su punto de entrada.
import '@fontsource/roboto/300.css';
import '@fontsource/roboto/400.css';
import '@fontsource/roboto/500.css';
import '@fontsource/roboto/700.css';
For more info check out Fontsource.
Fontsource can be configured to load specific subsets, weights and styles. Material-UI default typography configuration only relies on 300, 400, 500, and 700 font weights.
Componente
The Typography component makes it easy to apply a default set of font weights and sizes in your application.

overline textTema
In some situations you might not be able to use the Typography
component. Hopefully, you might be able to take advantage of the typography
keys of the theme.
{"This div's text looks like that of a button."}
Cambiando el elemento semántico
The Typography component uses the variantMapping
property to associate a UI variant with a semantic element. It's important to realize that the style of a typography component is independent from the semantic underlying element.
- You can change the underlying element for a one time occasion with the
component
property:
{/* There is already an h1 in the page, let's not duplicate it. */}
<Typography variant="h1" component="h2">
h1. */}
<Typography variant="h1" component="h2">
h1.
- You can change the mapping globally using the theme:
const theme = createMuiTheme({
props: {
MuiTypography: {
variantMapping: {
h1: 'h2',
h2: 'h2',
h3: 'h2',
h4: 'h2',
h5: 'h2',
h6: 'h2',
subtitle1: 'h2',
subtitle2: 'h2',
body1: 'span',
body2: 'span',
},
},
},
});
Adding & disabling variants
In addition to using the default typography variants, you can add custom ones, or disable any you don't need. See the Adding & disabling variants example for more info.
Accesibilidad
A few key factors to follow for an accessible typography:
- Color. Provide enough contrast between text and its background, check out the minimum recommended WCAG 2.0 color contrast ratio (4.5:1).
- Font size. Use relative units (rem) to accommodate the user's settings.
- Heading hierarchy. Don't skip heading levels. In order to solve this problem, you need to separate the semantics from the style.
