En Beamer, ¿cómo forzar que las etiquetas "enumerar" y "detallar" estén dentro del entorno en el que se mencionan?

Question

En la imagen siguiente, hay un marco personalizado definido mediante mdframedel paquete. Está claro que las enumeraciones salen del cuadro enmarcado.

Cuando se compone contenido similar con una clase normal, las etiquetas van dentro mdframeddel entorno.

Me gustaría obtener el mismo resultado excepto por la personalización de la etiqueta, excepto que la sangría de la etiqueta está alineada con el texto encima que comienza con "qué".

Answer 1

La idea del inmargintema es que elementos como los elementos enumerados se coloquen en la barra lateral, por lo tanto, el tema modifica, \leftmarginietc. Esto se puede deshacer parcialmente como se muestra en el código siguiente.

Algunos otros puntos:

• Si su versión de Beamer es razonablemente nueva, no la necesita \usepackage{etoolbox}, Beamer ahora ya carga esto.

• no necesitas \usepackage{graphicx}con proyector

• Usarlo multicolcon un proyector no tiene mucho sentido, el proyector tiene su propio mecanismo de columnas.
