I am doing a bit of custom dev focus on a set up from the Whitehouse WordPress theme. And, it seems that some style rules defined inside the theme are overriding various options that come with the tags I am using, which makes it very annoying to operate.

The cellspacing and cellpadding characteristics appear to become overridden, all content in table cells lines up towards the bottom, and strange gaps and spaces appear after various elements.

I'm not sure enough concerning the theme to be aware what rules are leading to which issues - can there be in whatever way to create a browser ignore ALL CSS terms for any specific element or elements except the inline terms I increase the tags myself?

the CELLSPACING and CELLPADDING characteristics appear to become overridden,

Yes, as the specification says: The UA might want to recognition presentational characteristics within an HTML source document. If that's the case, these characteristics are converted towards the corresponding CSS rules with specificity comparable to , and therefore are treated as though these were placed at the beginning of the writer style sheet

Make use of a DOM inspector for example Firebug, Dragonfly or even the ones included in Chrome, Safari and (recent versions of) Ie. They will explain which rules are put on which elements.

No, there's not.
