First method is you have which you could use is the Cascade, if you don't have control over which stylesheet would be loaded first then you can embed styles into the head of a particular page or use inline styles.. the nearer the style rule is to the HTML element it applies to the more authority it has (i.e. it will override).
Another way if you can't control the order of styles is loaded first then using specificity might also help you:
html body h1#header {color: #f00;}
would overide
h1#header {color: #00f}
no matter which order the stylesheets (or rules in a single stylesheet) are in because the first rule is using much more selectors making it more specific. Specificity [w3.org] used together with identifying body id's or classes can give control of singular pages, regardless of the cascade.
