Based on what you have said it sounds like you want this:
<ion-row style="height: 100%;">
<ion-col>
<p class="titulo-opcion">Venta Nueva</p>
<p>Permite el ingreso de Proyectos a clientes Nuevos o Existentes</p>
</ion-col>
</ion-row>
But I think you haven't worded it exactly so maybe this won't be the answer.
As I commented above please rewrite your question if this doesnt solve it.
