91 HTML: The html Tag The next line of your document is almost always the html tag <html>. This indicates where your html begins
92 HTML: The html Tag The next line of your document is almost always the html tag <html>. This indicates where your html begins It s closing tag is often the last line of your document
93 HTML: The Document Head The document head is a section beginning with <head> and ending with </head>.
94 HTML: The Document Head The document head is a section beginning with <head> and ending with </head>. The head contains information such as the title of the page which uses <title> and </title> tags.
95 HTML: The Document Head The document head is a section beginning with <head> and ending with </head>. The head contains information such as the title of the page which uses <title> and </title> tags. Advanced: It may also contain some content that does not display related to search engine optimization.
96 HTML: Document Bodies The document body is where all the major content goes. begins with the tag <body>
97 HTML: Document Bodies The document body is where all the major content goes. begins with the tag <body> ends with the tag </body>
98 HTML: Document Bodies The document body is where all the major content goes. begins with the tag <body> ends with the tag </body> contains a lot of different content.
99 HTML: Some body tags <p> this is a paragraph </p>
100 HTML: Some body tags <p> this is a paragraph </p> <h1> This is a Heading 1 </h1>
101 HTML: Some body tags <p> this is a paragraph </p> <h1> This is a Heading 1 </h1> <h2> This is a Heading 2 </h2>
102 HTML: Some body tags <p> this is a paragraph </p> <h1> This is a Heading 1 </h1> <h2> This is a Heading 2 </h2> same for h3 to h6.
103 HTML: Some body tags <p> this is a paragraph </p> <h1> This is a Heading 1 </h1> <h2> This is a Heading 2 </h2> same for h3 to h6. <br> This is a line break. It doesn t have a closing tag.
104 HTML: Inserting Images <img> is an image tag, but this tag has an attribute so we don t close it yet.
105 HTML: Inserting Images <img> is an image tag, but this tag has an attribute so we don t close it yet. <img src> src is the source attribute it gives information about where the image is located.
106 HTML: Inserting Images <img> is an image tag, but this tag has an attribute so we don t close it yet. <img src> src is the source attribute it gives information about where the image is located. for example src = assignment1.jpg would say the file is located in the same directory as the HTML.
107 HTML: Inserting Images <img> is an image tag, but this tag has an attribute so we don t close it yet. <img src> src is the source attribute it gives information about where the image is located. for example src = assignment1.jpg would say the file is located in the same directory as the HTML. Another important attribute is alt, which indicates alternate text to display if the image won t.
108 HTML: Inserting Images <img> is an image tag, but this tag has an attribute so we don t close it yet. <img src> src is the source attribute it gives information about where the image is located. for example src = assignment1.jpg would say the file is located in the same directory as the HTML. Another important attribute is alt, which indicates alternate text to display if the image won t. <img src = assignment1-1.jpg alt= A photo of grayscale by luminance >
