There is no <container> tag. When we use the term container, we’re talking about function. The header tag “contains” markup that goes at the top of the page. The <header> tag IS a container tag.
A div tag is a very general container. It stands for division. At one time, it was all we had so we used it exclusively and one page could have dozens of div tags in them. It got pretty confusing. In order to distinguish one div tag from another, we gave them id attributes.
<div id="header">Some content including a logo, page heading, and navigation also in a div tag</div>
<div id="aside">Some content</div>
<div id="article">Some content</div>
With the new version of HTML, we have additional tags that act as containers that have more meaning (semantic); header, section, article, aside, nav, footer, etc. In general, if there is a tag that makes more sense to use, i.e. a nav tag contains navigation code, then use it. If you need to put code in a container, and there is not a semantic tag that does the job, then use the div tag.
First I want to say it was a pleasure having you in class this semester. As I’m reading through the final reflective writing assignments I’m seeing common threads so I thought I would address some of the thoughts in this blog post so everyone has access to it following the close of the course.
This class has been an introduction to several different technologies. The objective was to give you an overview of how the different languages work together to create good content for today’s user agents (browsers). Here are a few summarizing thoughts:
Define the purpose of your site. What are the 1 or 2 primary focuses of the site?
The content should support the goal.
The media, images, features all should support the goals of the site. If the goal is to sell and you aren’t selling anything, then the site is not doing what you need it to do.
Organize the content, i.e. all media, images, forms, sections, articles, whatever so you know how the site should be layed out. How easy can you make it for your audience to get to the meat of the site? Don’t make them hunt.
HTML puts an element on a page. It gives structure to the content. Choose the right HTML element (tag) for the right job.
CSS contols layout and formatting. It contols the properties of the HTML elements; i.e. it controls the presentation of the structure.
JS is the client-side scripting language that we use to change or modify the HTML elements and their properties, based on events or conditions that exist; i.e. click a button – something happens.
Now you have the basic overview. You have a growing vocabulary and sense of what does what. Learning scales does not make you a musician. Knowing how and when to apply them in context does. Now you are ready to start practicing what you have learned.
Build web sites. Start building them for fun. Look at an ad in a magazine. How would you build it using HTML and CSS? Try it. You learn by doing. Following are other good resources to take you to the next level.
A list apart: One of the first online magazines dedicated to people who build websites for a living. (http://alistapart.com)
stackOverFlow.com: Good resource to getting answers to your coding issues. How do I do this? Stack Overflow probably has the answer. (http://stackoverflow.com)
Web Frameworks: You are not the first web designer to solve this issues. Many designers have build up a series of pages, CSS files, and supporting technologies that they use again and again to build their web sites quickly and reliabiltiy. They have made their systems avaiable to the community for free. Learn them and you’ll speed up your design time and your sites will look great. No need to re-invent the wheel; i.e. you want to. Twitter Bootstrap, and Foundation are popular ones. There are more coming all the time. Just do a Google search on HTML frameworks.
After you leaern the basics of JS, learn jQuery. It makes JS more accessible for non-programmers.
Get familiar with WordPress. It is an entry level CMS (Content Management System). Most web sites are created with CMS backends so the end user doesn’t have to code to post an article, blog, marketing info, create a portfolio, etc. If you want to work for an agency, they’ll want you to be comfortable with WordPress.
That’s it. Now. Go forth, learn some more stuff, and create.

Hosting and streaming video requires a lot of storage and bandwidth. Many shared hosting plans will allow you to host your video. In this instance, you would use the <video> tag to provide that content to your users. However the performance can sometimes be terrible because shared hosting can contain many web sites and are not optimized for media streaming. Streaming services like youTube, Vimeo, Blip, and other commercial solutions exist to provide the infrastructure to deliver your videos with good data throughput and buffering (i.e. without pauses). When using those services to deliver media, they will provide you with the necessary code to use to get the media content to play on your web site.
On the Youtube page there will be an option to share.
Under the share option are several options:
One of those options is an embed option which will provide a line of code (usually an iframe).
Note: Youtube utilizes both Flash technology and HTML5 technology. Flash technology is not mobile compatible; at least, not on iOS devices (which have a huge market share). To ensure your YouTube embedded videos are mobile compatible see the following article on Stack Overflow: http://stackoverflow.com/questions/13516345/howto-play-youtube-videos-via-html5-video-tag. The article explains how to ensure your videos are being streamed from YouTube using HTML5 technology and therefore mobile compatible.
There is more than one way to get video content onto your web site. The video tag is the method of choice if you happen to know the exact URI of your video content. However, many streaming services have their own infrastructure and will provide a block of code that you can use to deliver the content onto your page.
