The document discusses various semantic markup elements used in web pages, emphasizing their importance for better content description for programs like screen readers and search engines. Key elements covered include <strong> for strong importance, <em> for emphasis, <blockquote> and <q> for quotations, <abbr> and <acronym> for abbreviations, <cite> for citations, <dfn> for definitions, <address> for author contact details, <ins> and <del> for inserted and deleted content, and <s> for deprecated content. Each section provides examples to illustrate the usage of these elements.
Semantic markup language
- 1. SEMANTIC MARKUP Presented By:Nabin jamkatel
- 2. Introduction • There are some text elements that are not intended to affect the structure of your web pages, but they do add extra information to the pages they are known as semantic markup. • The reason for using these markup is that other programs, such as screen readers or search engines, can use this extra information. • Its purpose is to describe the content of your web pages more accurately.
- 3. STRONG<strong> • The use of the <strong> element indicates that its content has strong importance. • For example, the words contained in this element might be said with strong emphasis. • By default, browsers will show the contents of a <strong> element in bold. • Example <p><strong>Beware:</strong> Pickpockets operate in this area.</p> <p>This toy has many small pieces and is <strong>not suitable for children under five years old. </strong></p>
- 4. EMPHASIS<em> • The <em> element indicates emphasis that subtly changes the meaning of a sentence. • By default browsers will show the contents of an <em> element in italic. • Example <p>I <em>think</em> Ivy was the first.</p> <p>I think <em>Ivy</em> was the first.</p> <p>I think Ivy was the <em>first</em>.</p>
- 5. QUOTATIONS • There are two elements commonly used for marking up quotations: 1. <blockquote> 2. <q>
- 6. <blockquote> • The <blockquote> element is used for longer quotes that take up an entire paragraph. • Note how the <p> element is still used inside the <blockquote> element. • Browsers tend to indent the contents of the <blockquote> element. • Example <blockquote cite="http://en.wikipedia.org/wiki/ Winnie-the-Pooh"> <p>Did you ever stop to think, and forget to start again?</p> </blockquote>
- 7. <q> • The <q> element is used for shorter quotes that sit within a paragraph. Browsers are supposed to put quotes around the <q> element • Internet Explorer does not support <q> therefore many people avoid using the <q> element. • Example <p>As A.A. Milne said, <q>Some people talk to animals. Not many l though. That's the problem.</q></p>
- 8. ABBREVIATIONS <abbr>& ACRONYMS<acronym> • If you use an abbreviation or an acronym, then the <abbr> element can be used. • A title attribute on the opening tag is used to specify the full term. • Example <p><abbr title="Professor">Prof</abbr> Stephen Hawking is a theoretical physicist and cosmologist.</p> <p><acronym title="National Aeronautics and Space Administration">NASA</acronym> do some crazy space stuff.</p>
- 9. CITATIONS<cite> • When you are referencing a piece of work such as a book, film or research paper, the <cite> element can be used to indicate where the citation is from. • Browsers will render the content of a <cite> element in italic • Example <p><cite>A Brief History of Time</cite> by Stephen Hawking has sold over ten million copies worldwide.</p>
- 10. DEFINITIONS<dfn> • The first time you explain some new terminology (perhaps an academic concept or some jargon) in a document, it is known as the defining instance of it. • The <dfn> element is used to indicate the defining instance of a new term. • Example <p>A <dfn>black hole</dfn> is a region of space from which nothing, not even light, can escape.</p>
- 11. AUTHOR DETAILS<address> • The <address> element has quite a specific use: to contain contact details for the author of the page. • It can contain a physical address, but it does not have to. • For example, it may also contain a phone number or email address. • Example • <address> • <p><a href="mailto:[email protected]"> [email protected]</a></p> • <p>742 Evergreen Terrace, Springfield.</p> </address>
- 12. <ins> and <del> • The <ins> element can be used to show content that has been inserted into a document, • while the <del> element can show text that has been deleted from it. • The content of a <ins> element is usually underlined, • while the content of a <del> element usually has a line through it. • Example <p>It was the <del>worst</del> <ins>best</ins> idea she had ever had.</p>
- 13. <s> • The <s> element indicates something that is no longer accurate or relevant (but that should not be deleted). • Visually the content of an <s> element will usually be displayed with a line through the center. • Example <p>Laptop computer:</p> <p><s>Was RS 995</s></p> <p>Now only RS 375</p>
