In this tutorial, I am going to show you how to add a Java applet that will play in both Internet Explorer and Firefox as well as other types of browsers and will also validate. We will need to use the <object> tag and its attributes classid, type, width, and height. We will also need the <param> tag and its required name attribute along with the value attribute. We will also need one more thing, which is Internet Explorer’s conditional comments, which I will explain in a bit.

Before I begin, Java is not JavaScript they are two completely different types of technologies. Java is used to create small applications like applets, calculators, clocks, drawing shapes and other types of special effects and more that you can embed and run in your browser. I can write a whole book about Java but in this tutorial, I will just explain how to embed a Java applet to your web page.

Now the second method for embedding Flash movies to your web pages involves using the <object> and <param> tags along with their attributes. For instance, the <object> tag has four required attributes, which include height, width, classid and codebase. And the <param> tag has two attributes, which include the required name attribute along with the value attribute. Let me explain the <object> tag and its attributes first and then I will explain the <param> tag and its attributes.

Another, some what simple way to add playable videos to your web pages involves using the <object> and <param> tags along with their attributes that include data, width, height and the required type attribute for the <object> tag. And the value attribute along with the required name attribute for the <param> tag. The <object> and <param> tags are the recommended way to display videos on your web page, unlike the <embed> tag, which is a non-standard tag.

You can also add music to your web page by using the <object> and <param> tags and their attributes. The <object> tag will need the width, height and data attributes. And the <param> tag will need the name and value attributes. Let me explain the <object> tag and its attributes first.

Now the second method of adding a background sound clip to your web page works in Internet Explorer, the dead and departed Netscape, Opera and Firefox as well as other browsers. In order to add a background sound clip to your web page we will need the <object> tag along with its width, height and data attributes. We will also need three <param> tags along with its name and value attributes.

Okay, what if you don’t want search engines indexing your web pages for some reason. This is why the robots <meta> tag was created to stop search engine spiders also known as robots, which are automated mechanisms that spider your site to list in the search engines.

You can also tell search engine spiders when to come back to your web site and re-index your web pages. In order to accomplish this you will need to use the revisit-after <meta> tag. One more thing you should know before I explain the revisit-after <meta> tag is that major search engines are thought not to support the revisit-after <meta> tag, but it never hurts to include the revisit-after <meta> tag anyway.

The purpose of the author <meta> tag is to indicate who created the web page by providing one of the following formats which include the author’s full name, email address, company name or URL address in the <meta> tag. The most common format is to provide the author’s full name or company with an email address, but it’s not recommended to include the email address due to spamming. The author <meta> tag is not supported by the major search engines but it is still considered a <meta> tag standard.

The copyright <meta> tag is not the best way to copyright protect your web page. It’s more of a way to state that your web page has been, trademarked, copyrighted, patented or anything pertaining to your intellectual property.
