Transcript of HTML - Introduction

The Internet The Internet (sometimes called"the net" for short) is a network of computers linked together. It started in 1969 as a US military ecperiment to share computer resources more effiently. later, it was epaned to include colleges and research facilities Today, the Net has grown into a massive public broadcast medium. its is an international network of mied compute technology with more than 600 million users using several different computer called protocols. HTML is one protocol. Where did HTML come from? HTML Hyper TEXT Markup Language is a set of tags used to create a Web page. Web Page A web page can be useful in both business and personal use. Web pages are becoming increasingly popular as the cost of web hosting is dropping and more free tools are available for website building. You do not have to be an expert in web pages in order to have one. Business A business web page can provide customers with 24/7 information about the company and services it offers. Competition A professional and attractive website can help you get ahead of competition. Search engine optimization can be utilized to bring your business website up as a top search result, before your competitor's website. Marketing Marketing can be a purpose of a business web page. Utilize strategies such as exclusive coupons and discounts offered to customers who visit the website. Sales A business web page can serve a sales purpose. Use an e-commerce shopping cart, such as Zen Cart, in order to sell items online. Paypal.com is a popular online payment system, but you can also add credit card processing using third-party solutions, such as 2checkout.com Personal Blog A web page can also be a personal or family-related blog. A family can post childrens' milestones or pictures for family members to see. It can also be used to notify relatives of the family's updates and exciting adventures. Portfolio Freelancers such as writers, graphic designers and web designers can build online portfolios to direct their clients to. An online portfolio for a freelance writer can consist of writing samples, and web designers can show off completed web pages for other clients. The Web Development Cycle Each document you produce in HTML is considered to be one web page …no matter how long or short it is. An entire group of web pages collected at one location is called a web site (or just “site” for short.) There are four major stages in the web development cycle Planning — Writing a web page is simple, however, if you want to create a good site, you will need to put some planning into it. You need to decide what you want to say, organize your thoughts, research what you want it to look like and decide what should be linked to what. This should all be done in the planning stage. Creating —After the web site is planned, you need to write the text and format it with HTML commands. You will also need to gather or create the graphics you
will use in your site. Testing —After each page is created, you will need to test it on one or more different browsers to make sure it looks and acts like you want it to. You can do the initial testing off-line, on your computer and correct any mistakes before you publish Publishing —Publishing a web site is similar to publishing a book…you make it
available to anyone who wants to see it by uploading , or moving your finished
page (or pages) from your computer to a web server. A web server is simply a
computer whose job it is to send the file to any computer asking to look at it. In creating complicated web pages, it's not unusual for the web page creator to write part of the page, test it, and then write more. The writing and testing stages of the
web development cycle usually take the most amount of time. Tags What makes HTML documents different than ordinary ones is that formatting
commands are written into the file. These commands, called tags , tell the browser
how to display the document. You can think of a browser as an obedient, very bright, but very literal, child. It will
do what you say exactly the way you say to do it. It “knows how” to do many
complicated things, but you must tell it explicitly to do something or the results will
not be what you think they should be. You can tell which words are tags in HTML because they have angle brackets around
them,<>. Angle bracket look like "Less than" and greater than signs. These bracket tell your web browser to use these command to interpret and display your page. The angle brackets are followed by the name of the tag itself. While most browsers do not "see" a difference between tags written in uppercase and those written in lowercase, it is considered "good practice" to write your tags in lowercase. After the tag and within the angle brackets you may find information that modifies the tag or gives specific information that the browser needs to execute the tag. This information is called an attribute. Most tags have a few attributes, many of them optional. Attributes usually need further information, called values . Values can be numerical (percentages or measurements) or a specific set of words (“left,” “right,” or “center.”) With a few exceptions, values are always surrounded by double quotes. For nearly every tag, there is an equivalent closing tag . Closing tags tell the browser
when to stop doing something. For example, the closing paragraph tag tells thebrowser where the end of the paragraph is. Document Tags HTML The Introduction
