Welcome! And this quote above. Awesome. I wish I was old enough to the lady that does that.

I personally code in Dreamweaver, mostly because I am not the most proficient with CSS and find it's easier to deal with Dreamweaver.
I also personally hate Flash. It's obnoxious and annoying.
That said... it's very popular.
I"m not sure what the "industry standard" is right now.
Mostly I'd say if you can code it and it doesn't look circa 1999 you're probably alright.
But perhaps someone who is a web guru will also post and give us their opinion?

Key aspects of following industry needs involves writing semantic mark-up and separating structure from presentation using external stylesheets. A machine can't write semantic mark-up so its always best to code by hand. It will result in more robust, clean and lean code then any machine can provide. Resulting in a higher level of SEO, maintainable and stability for years to come.

There also seem to be an increasing push for progressive enhancement vs. graceful degradation. Technology seems to be changing so quickly that its more beneficial to force people to upgrade out dated and non compliant browsers then it is to consider them in the same respect to newer technologies.

A trend I have noticed recently is the desire to support future technologies using the technologies of today. An example is using JavaScript to support selectors or styles planned for CSS3.

What do you mean by "semantic markup"?

The one thing I never really "got" about CSS is why it's any better than using tables to do layouts.

Code that describes the context of the content which it encapsulates.

HTML is a structural construct not a presentational one. The sole purpose of HTML is to describe and organize content. The purpose of CSS is to provide a presentation for that structure. The separation of structure and presentation results in a more maintainable, changeable and purposeful application.

People need to stop thinking about this as divs vs. tables. Its not about divs and its not about tables. Its about writing code that machines can better understand and place context to. A practice that results in a more findable, accessible and useful web experience.

HTML, Javascript and some form of content management system.

It's easier to manage pages, whether a handful or a thousand, if all the layout information is in one file. It also makes pages easier to parse for normal people and search engine spiders.

Imagine a bank of televisions at an electronics store. Each television is tuned to play the same video. Would you rather have each TV have its own video player and video inside it, or would you rather have each TV connected by a network to one master video player?
