From a designer’s viewpoint, forms let you establish a dialog with your site’s visitors.
Instead of using text and pictures to send information, forms let you use text boxes, check
boxes, radio buttons, and selection menus to retrieve information.

Frames:
Frames divide a browser window into two or more separate pieces or panes, with each
pane containing a separate web page. One of the key advantages that frames offer is
that you can load and reload single panes without having to reload the entire contents
of the browser window. A collection of frames in the browser window is known as a
frameset .](https://image.slidesharecdn.com/html-120607095856-phpapp02/75/Html-6-2048.jpg)

Html
HTML is the standard markup language used to create web pages. HTML documents are composed of elements like headings, paragraphs, links etc that provide structure and meaning. A web browser reads the HTML tags and displays the page by interpreting the tags. Common HTML elements include headings, paragraphs, images, hyperlinks, tables, forms and lists that are used to structure and layout the content on a web page.

- 1. HTML- Concept ofHypertext HTML, which stands for HyperText Markup Language, is the predominant markup languagefor web pages. HTML is the basic building-blocks of webpages. HTML is written in the form of HTML elements consisting of tags, enclosed in angle brackets(like <html>), within the web page content. HTML tags normally come in pairs like <h1> and </h1>. The first tag in a pair is the start tag, the second tag is the end tag (they are also calledopening tags and closing tags). The purpose of a web browser is to read HTML documents and compose them into visual or audible web pages. The browser does not display the HTML tags, but uses the tags to interpret the content of the page. HTML elements form the building blocks of all websites. HTML allows images and objects to be embedded and can be used to create interactive forms. It provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes and other items. It can embed scripts in languages such as JavaScript which affect the behavior of HTML webpages. Elements HTML documents are composed entirely of HTML elements that, in their most general form have three components: a pair of element tags, a "start tag" and "end tag"; some element attributes within the start tag; and finally, any textual and graphical content between the start and end tags. The HTML element is everything between and including the tags. Each tag is enclosed in angle brackets. A pair of tags and the content these include are known as an element . HTML section tags To organize the various parts of HTML that describes a Web page, we use a set of section tags. The types of html tags in each section of web page definition have a specifics purpose:
- 2. 1- <html></html> Theseoccur at the start and end of an HTML document. Start and end html tags enclose all the other html tags we use to describe the web page. 2- <head></head> Start and end header tag immediately follow the start HTML tag (<html>) and denote the web page header. We can use tags in the web page header to include such information as the name of author and date of the created page. In addition, we insert tags with information that describes your page so that Web search engines can add references to your page to their search indexes. Of the HTML tags and information you place in the header section, the visitor’s browser displays only the Web page title. You insert the Web page title in the header section between start and end title tags (<title></title>), as shown in the code sample that follows this list of section tags. 3- <body></body> Start and end body tag immediately follow the web page header section and denote the web page body. The body section of the web page contains the tags that tells the web browser what to display onscreen and how we want it to look. The < head > element: Often referred to as the head of the page, this contains information about the page (this is not the main content of the page). For example, it might contain a title and a description of the page, or instructions on where a browser can find CSS rules that explain how the document should look. It consists of the opening < head > tag, the closing < /head > tag, and everything in between. The < body > element: Often referred to as the body of the page, this contains the information you actually see in the main browser window. It consists of the opening < body > tag, closing < /body > tag, and everything in between Building HTML document:- HTML text documents are actually quite simple to create. To create an HTML document, you open a text-editing program and then type in the HTML code. After you have entered the HTML statements, you save your document as a text file with an .htm or .html extension. For example, start
- 3. your favorite texteditor (such as Windows Notepad) now, and enter the following HTML: <html> <head> <title>Example of a Simple HTML Document</title> </head> <body> <p>HELLO WORLD! Here I am.</p> </body> </html> Now, save your work to a Web page file (that is, a file with an .htm or .html extension) on your hard drive. Create a folder (such as C:HTMLExamples) in which to store the Web pages. Then, save the code you entered for this example as TestPage.htm in the folder you create. Then start your Web browser, and type File:// followed by the drive letter and pathname of your Web page into the browser’s Address field. For example, if you saved the Web page in this example as TestPage.htm in the C:HTMLExamples folder, type File://c:/HTMLExamples/TestPage.htm into the browser’s Address field. Then, press ENTER. Your Web browser, in turn, will display the Web page. Inserting text: In standard word processing, a paragraph defines a group of sentences. Typically, a blank line or an indented first word identifies the start of a new paragraph. When you insert text into a Web page, the </p> tag controls the end of text and the subsequent beginning of the next paragraph. The </p> tag instructs the Web browser to move down one line, insert a blank line, and then to begin the next paragraph on the line below the blank line for the text following the </p> tag. For eg: <html> <head> <title>Welcome to Lots of Text </title> </head> <body>
- 4. <p>The text betweenthe two paragraph tags defines a single paragraph. Paragraphs contain one or more sentences</p> <p>The next paragraph starts here with a blank line inserted between the two paragraphs</p> </body> </html> HTML also has several text formatting tags you can use to change the appearance of text, usually for emphasis. To apply a formatting style, place the format’s start tag at the beginning of the text you want to style. The following list describes three of the most common formatting tags. • <b></b> Text placed between the Bold tags is displayed in bold font. • <i></i> Text placed between the Italic tags is displayed in italic font. • <u></u> Text placed between the Underline tags is displayed with an underline. Images: For eg: <html> <head> <title> Example of text and graphic placement </title> </head> <body> <img src="flower.jpg"> </body> </html> Hyperlinks: A hypertext link is a single word or a group of words upon which a visitor clicks to instruct the Web browser to retrieve a Web page (or other file) from the Web server.
- 5. <a href="info.htm">Click hereto move to the next page.</a> Table: The HTML tables you use to display content on a Web page, like the tables you see in printed materials consist of columns of data arranged in rows. • <table></table> Alert the Web browser that it is to treat the text between the start and end tags as a table • <tr></tr> (table row) Alert the Web browser that it is to put the data items and perhaps headings between the start and end tags on a single, new row in the table • <td></td> (table data) Alert the Web browser that the HTML tags, attributes, and text (if any) between the start and end tags is content (in other words, the data) that the Web browser is to display in a table column For example, you would write the following HTML code to have a Web browser display the simple three-column, two-row table shown here: <table border="1"> <tr><td>1</td> <td>2</td> <td>3</td></tr> <tr><td>4</td> <td>5</td> <td>6</td></tr> </table> • border Attribute in a <table> tag that tells the Web browser the number of pixels wide to draw the border around the perimeter of the table and each of the table’s cells • <caption> </caption> Alert the Web browser that it is to style the text between the start and end tags as a caption (most browsers use a boldface font) • <th></th> (table heading) Alert the Web browser that the text between the start and end tags is to be formatted as heading text (most browsers use a boldface font) <table border="1" > <caption>Tags and Attributes Used to Create a Table</caption> <tr><th>HTML Tag</th> <th>Description</th></tr>

A collection of frames in the browser window is known as a frameset .
- 7. A frameset dividesthe window into rows and columns (rather like a table). The simplest of framesets might just divide the screen into two rows, whereas a complex frameset could use several rows and columns. < html > < head > < title > Frames example < /title > < /head > < frameset rows=”150, *, 100” > < frame src=”top_frame.html” / > < frame src=”main_frame.html” / > < frame src=”bottom_frame.html” / > < noframes > < body > This site uses a technology called frames. Unfortunately, your browser does not support this technology. Please upgrade your browser and visit us again! < /body > < /noframes > < /frameset > < /html > The border attribute specifies the width of the border of each frame in pixels. border=”10” The frameborder attribute specifies whether a border should be displayed between frames. The following indicates that there should not be any borders (which is the same as if the border attribute is given a value of 0 ): frameborder=”0” List: You can create three types of lists in XHTML: Unordered lists , which are like lists of bullet points
- 8. Ordered lists ,which use a sequence of numbers or letters instead of bullet points Definition lists , which allow you to specify a term and its definition < ul > < li > Bullet point number one < /li > < li > Bullet point number two < /li > < li > Bullet point number three < /li > < /ul > < ol > < li > Point number one < /li > < li > Point number two < /li > < li > Point number three < /li > < /ol > < ol type=”i” > < li > Point number one < /li > < li > Point number two < /li > < li > Point number three < /li > < /ol > < ol type=”A” start=”4” > < li > Point number one < /li > < li > Point number two < /li > < li > Point number three < /li > < /ol >
