If you want to see how I have used this language to make this page. The first tag is used to start the effect you want to make and the second tag is used to end the effect. All the text in these tags is underlined. Second thing you need to learn is that when you want to use more then one effect on same thing you don't use diffrent tags. If you do it like this then only one tag will work depending on your browser.
Third thing is that some of the tags desn't requires the second tag with slash in it.
This will put your image file named myimage.jpg into your document. For this I didn't need any second tag with slash in it. Now you might wanna give it a try. This will let your browser know that the document between these tags is going to be HTML document. After this you might want to decide what should be your background's color, text's color and link's color.
