INTRODUCTION
HTML stands for Hyper Text Markup Language
predominant markup language for web pages
Developed by World Wide Web Consortium & WHATWG
Type of format Markup language
HTML Tags
HTML markup tags are usually called HTML tags
HTML tags are keywords surrounded by angle brackets like <html>
HTML tags normally come in pairs like <b> and </b>
The first tag in a pair is the start tag, the second tag is the end tag
Start and end tags are also called opening tags and closing tags
HTML tags are not case sensitive
HTML Headings
HTML headings are defined with the <h1> to <h6> tags.
HTML Paragraphs
HTML paragraphs are defined with the <p> tag.
HTML Links
HTML links are defined with the <a> tag.
HTML Images
HTML images are defined with the <img> tag.
HTML Comments
Comments can be inserted in the HTML code to make it more readable and understandable but they are ignored by the browser and are not displayed.
HTML Element
An HTML element starts with a start tag / opening tag and ends with an end tag / closing tag
The element content is everything between the start and the end tag
Some HTML elements have empty content . Eg.line break
Empty elements are closed in the start tag
Most HTML elements can have attributes
HTML Attributes
Attributes provide additional information about the element
Attributes are always specified in the start tag
Attributes come in name/value pairs like: name="value"
HTML links are defined with the <a> tag.
Eg. <a href="http://www.w3schools.com">This is a link</a>
HTML Styles
Styles was introduced to style HTML elements using the style attribute, or indirectly in separate style sheets (CSS)
Style Examples:
I. Background Color
II.Font Family, Color and Size
III.Text Alignment
HTML Links
Link syntax:
<a href="url">Link text</a>
A hyperlink is an address to a resource on the web.
An anchor is a term used to define a hyperlink destination inside a document.
The HTML anchor element <a>, is used to define both hyperlinks and anchors.
HTML Images
In HTML, images are defined with the <img> tag.
To display an image on a page, you need to use the src attribute. Src stands for "source". The value of the src attribute is the URL of the image
The syntax of defining an image:
<img src="url" />
The browser puts the image where the image tag occurs in the document.
The alt attribute is used to define an "alternate text" for an image. The "alt" attribute gives information of what is missing on a page if the browser can't load images.
HTML Tables
Tables are defined with the <table> tag. A table is divided into rows (with <tr> tag), and each row is divided into data cells (with <td> tag) where td stands for "table data," which is the content of a data cell.
Headings in a Table
Headings in a table are defined with the <th> tag.
HTML Lists
Unordered Lists
An unordered list is a list of items marked with bullets.
An unordered list starts with the <ul> tag. Each list item starts with the <li> tag.
<ul><li>Coffee</li></ul>
Coffee
Ordered Lists
An ordered list is also a list of items marked with numbers.
An ordered list starts with the <ol> tag. Each list item starts with the <li> tag.
<ol><li>Coffee</li></ol>
1.Coffee
Definition Lists
A definition list is not a list of single items. It is a list of items with a description of each item.
A definition list starts with a <dl> tag (definition list).
Each term starts with a <dt> tag (definition term).
Each description starts with a <dd> tag (definition description).
<dl><dt>Coffee</dt><dd>Black hot drink</dd></dl>
Coffee
Black hot drink
HTML Forms and Input
A form is an area that can contain form elements that allow the user to enter information (like text fields, textarea fields,radio buttons, checkboxes) in a form.
A form is defined with the <form> tag.
The most used form tag is the <input> tag.
When the user clicks on the "Submit" button, the content of the form is sent to the server.
HTML Colors
HTML colors are defined using a hexadecimal notation for the combination of Red, Green, and Blue color values.
The lowest value to the light sources is 0 and highest value is 255.
Hex values are written as 3 double digit numbers, starting with a # sign.
It gives a total of more than 16 million different colors to play with (256 x 256 x 256).
HTML Frames
With frames, we can display more than one HTML document in the same browser window. Each HTML document is called a frame, and each frame is independent of the others.
The <frameset> tag defines how to divide the window into frames
The <frame> tag defines what HTML document to put into each frame
The disadvantages of using frames are:
I. The web developer must keep track of more HTML documents
II. It is difficult to print the entire page
