[Regarding Wordpress MySQL database transfer from dev to production site] I've created a site in WordPress on our development machine. In the theme we're using there are numerous widget zones to display text in (sidebar and front page). I've used simple Text widgets in all of these zones to put our display information.
When I migrated the site to production, I used the WP-DB-Backup plugin to take a snapshot of the database. I then edited the resulting .sql file to update all of the file paths and URL references to point to our production site.
After creating the database, website, and copying all of the files over to the production site, I run the .sql file from the mysql command prompt to import the data into the new database.

Even though browsers do start with inconsistent defaults, it’s possible to override them. In the hierarchy of CSS specificity, the browser’s default stylesheet is at the very bottom. Any inline or externally defined styles will override browser defaults.

With the ability to override those default styles, you’re able to explicitly define a new set of your own default rendering styles. Instead of allowing each browser to decide how much space should be above and below block level elements, for example, you have the opportunity to preemptively dictate styling that renders identically across all browsers.

In other words, there’s nothing preventing you from resetting all of the default styling for HTML elements to a predictable baseline style. In fact, doing so will almost entirely negate the cross-browser variances in default styling.

This technique is called a CSS reset.

instead of hacking the core, a simple plugin should do the trick. try this for size. install in the normal way.

If you move your WordPress website to a new domain name, you will find that internal links to pages and references to images are not updated. Instead, these links and references will point to your old domain name. This plugin fixes that problem by helping you change old urls and links in your website.

The tricky thing is this particular copy of jQuery is in compatibility mode by default. That means that the typical ‘$’ shortcut for jQuery doesn’t work, so it doesn’t conflict with any other JavaScript libraries that use the dollar sign also, like MooTools or Prototype.
Many plugin authors and theme developers are aware of this, and they use ‘jQuery’ instead of ‘$’ to be safe.
