ample uses the src (source) attribute to tell the browser that the image that you want to display is the image.jpg
file. You use the width attribute, with a value of 300 , to tell the browser that your image should be displayed 300
pixels wide, and the height attribute with a value of 100 to make it 100 pixels tall. The value of the alt attrib-
ute here provides some text that the browser might display if the image cannot be loaded. You learn more about the
<img> element, as well as lots of other content elements, in Chapter 4.
The <html> element is often used to define the language of the content within the document. This is done by
adding a lang attribute to the start tag that has a two-character language code as its value. (This applies only to the
actual page content and not to the tag names; they should always be written in English.) The following example
defines the content language as English by adding the lang attribute with the value ”en” . (I highlight the new por-
tion of the code with each new example so you can identify it easily.)
<html lang="en">

The <head> Element
The first element contained within the <html> element should be a <head> element. This element contains in-
formation about the page, such as the title. Here's the <head> element from the sample code:
<title>My First Web Page</title>
