So having completed Part 1, Part 2, Part 3 and Part 4 of this series of web development tutorials, we’re finally able to actually construct a webpage. Now I said that we’d look at CSS in this tutorial, and we will, but first off let’s build a basic webpage that we can use to experiment with later.Comments: none yet | Filed under: tutorials | Tagged: css, html, properties, selectors, values, web design, web development

So having completed both Part 1 and Part 2 as well as Part 3 of this series of web development tutorials, we can now move on to discuss even more HTML elements. In the next part of this series, we’ll look at CSS, and finally make our webpages pretty.
The ‘Image’ element <img> allows us to embed images into our webpage. The image source is specified in the same way a link ‘href’ is, but the ‘src’ attribute is used instead:
<img src="image.png" alt="Non visual browsers see this">
The ‘alt’ tag specifies what to show if the image fails to load or cannot be shown. Note that the <img> tag is a void tag, and does not need closing. The images must be in a format readable by the browser, for example PNG, GIF or JPG.
The ‘Video’ element <video> allows us to embed videos into our webpage. This element acts similarly to the ‘Image’ element, and also has a ‘src’ attribute:
Your browser does not support <video>.
The ‘alt’ text is simply contained within the element, and will display on browsers that don’t support the element. Embedded videos must encoded in a way that the browser can understand, for example H.264.Comments: none yet | Filed under: tutorials | Tagged: audio, elements, form, html, image, table, video

Text-level semantic elements allow us to describe the meaning of text content in our document. We can say that some particular words are more important than others, that a line break should go here, that this bit here is a quote, etc. We won’t be discussing all of the elements that can be used, but we’ll cover the most important.
The anchor element
The anchor element is represented by the ‘a’ tag, and is displayed as a hyperlink which can lead to other webpages – creating that web of links you’ve heard that’s world-wide. The anchor element has a ‘href’ attribute which indicates the webpage to link to. It’s used like this:

<a href="someotherpage.html">This link takes you to some other page</a>

So having completed Part 1 of this series of web development tutorials, we can now begin to get some actual coding done, remembering of course that since we’re just using HTML and not CSS, we won’t be able to create a particularly attractive webpage, but we’ll at least have a foundation upon which we can further our knowledge.
We’ll start by examining the most basic HTML document usable practically. It looks like this:
<p>This is a paragraph.</p>
Paste that into a file with the extension ‘.html’, and open it up in your favourite web browser – you can use a program like Notepad++ to do this (just switch the language to HTML). Note that when you do this, your browser is directly interpreting the file itself – there’s no request to a server or anything, so this is purely client-side.Comments: none yet | Filed under: tutorials | Tagged: attributes, elements, html, tags, web design, web development

So beginning (hopefully) a series of tutorials on web development, we look at an overview of how websites are constructed and what interaction occurs between a web browser and a web server.
Basically, the world wide web is based on a client-server architecture, where the client (the web browser) requests data from a server (the website) which, in turn, sends a response containing the data.
Of course, this is a greatly simplified explanation of what’s going on (it’s not really as direct as it appears here), but such an understanding will suffice for developing most websites.
