#fix { height: 200px; width: 500px; position: fixed; background-color: blue; margin-bottom: 200px; } #text { background-color: green; width: 500px; height: 700px; }

¿Por qué esto en el ejemplo no funciona el margen? Ahora div #fix para cubrir div #text. Me gustaría hacer un margen. La cubierta debe ser solo si la página está en la parte inferior, etc.

Creo que esto podría funcionar para ti …

 #fix {height: 200px; width: 500px; position: fixed; background-color: blue; top:0; left:0;} #text {background-color: green;margin-top:200px; width: 500px; height: 700px } 

Es debido a la position: fixed; código. El navegador no puede hacer el cálculo correcto con margen mientras está arreglado. Quítalo y funciona.

Eliminar la posición fija
