Learning Aim C

 In this section we will look at some simple client-side scripts, browser compatibility, exporting and compressing and suitable file types.

 Scripts which run on the client's (user's) computer can do a number of things.  We have already used built-in scripts to make a menu bar and open a browser window and there are quite a few others included in Adobe® Dreamweaver®, including ones to validate form entries.  You can add your own scripts written in languages especially designed for web page scripts, like Java Script and AJAX.

 You can find many JavaScript examples on the internet.

 There are many different browsers in use (Explorer, Firefox, Chrome, etc. ).  Not all HTML features are supported by all browsers and older versions of browsers will not support the newer features.  To ensure your web pages are compatible with different browsers, you need to load each page into a selection of the most popular browsers to see it they load correctly and display as you expect.

 Digital assets such as images, audio clips and videos need to be prepared for inclusion in a web page.  These assets often have large file sizes and may take a long time to download unless they are compressed.  Image and video files need to be set to a suitable size and resolution to make sure their file size is not unnecessarily large.

 Although you can preview your web pages in a browser locally on your computer, your web pages need to be uploaded on to a web server before they are available on the internet.  In addition, you will need to choose a web hosting company.

 Many organisations run web servers and offer a web hosting service.  Most charge for this, although some offer the service for free (but include adverts in the pages).

 Having chosen a web hosting company you will then need to up load your website files (everything contained in the local website folder, including images and other media) to the hosting company's servers.  This is normally done using a web-based control panel program provided by the web hosting company.

 Simply uploading your pages on to a web server won't make them available on the internet, because no one will be able to find them.  Your site will need to be assigned a domain name, which is unique to the site.
