❃TAGS, ELEMENTS, AND ATTRIBUTES
HTML code is made up of elements, tags, and attributes.
❍TAGS,
Tags are the building blocks of a web page. They contain elements that define how the information on a web page is Formatted or displayed.
Each tag in HTML follows specific rules and syntax. These tags are not case sensitive, for example <tag name and <TAG NAME> will have the same effect.
The HTML tags or commands are inserted before and after the text. Each tag, giving a specific instruction, begins with a less than sign'<'and ends with a greater than sign'>'
For example: The tag for defining a paragraph is <p>.
You should use <p> before the block of text that you want to designate as a paragraph. This is the opening tag or the on tag. At the end of the text block, you place </p>. you will type the following in the text editor:
SYNTAX: <p> some text</p>
━━━━━━━━━━━━━━━━━━━━━
❍ELEMENTS
An HTML element consists of an on tag, the content, and an off tag.
The HTML elements can be categorised as:
- Container Elements
- Empty Elements
❍Container Elements
The elements that include both on and off tags are called Container Elements.
E.g. <b> This makes the text bold </b>
❍Empty Elements
Empty elements contain only on tags. They do not have off tags. These elements do no enclose any data; instead they do some function on their own.
For example, <br> tag (It breaks the line and displays the text from the next line.)
━━━━━━━━━━━━━━━━━━━━━
❍ATTRIBUTE
An Attribute is the property that provides additional information about an HTML element Yt enhances the functionality of a tag.
always enclosed within quotes.
For example, the width attribute of the <hr> tag specifies the width of the horizontal line in pixels or percentage. By default, the width of the horizontal rule is 100%. So, if you write <hr width=50%>, the horizontal line will cover only 50% of the page. You can use more than one attribute inside a tag.
━━━━━━━━━━━━━━━━━━━━━
❃RULES FOR WRITING HTML CODE
- Tags and attribute names are not case-sensitive, so <Head>, and <head> have the same meaning. However, using lower case is recommended
- Container tags should always be closed because an unclosed tag can lead to undesired results.
- Values given to the attributes should be enclosed within quotes, especially if the value contains any blank space.
- Attribute values can be case sensitive
- When the tags are embedded, ie; when you start a tag within another tag, you need to close the inner tag before closing the outer tag.
- Tag names should not contain spaces, For example, writing <body> as <body> is incorrect
- There should be no space between '<, name of the tag, and > in a tag. For example, writing <p> as <p> is incorrect.
