don't override an explicit width or height

[dabrahams]

I placed an image in my slide using style='position: absolute...' and explicit width and height attributes but it didn't show up. Turns out markdown wrapped it in a <p>, whose size was then zero… which then forced the image size to zero.

I'm not sure this is really what's needed, because it seems like width or height specified in non-absolute units like '%' or 'em' should probably be limited by minima/maxima. I'm not a CSS expert, so maybe there's a better remedy out there.

Coloqué una imagen en mi diapositiva usando atributos style='position: absolute...'explícitos widthy heightpero no apareció. Resulta que Markdown lo envolvió en un <p>, cuyo tamaño era entonces cero... lo que luego forzó el tamaño de la imagen a cero.
