HTML has six "levels" of headings:
To create a paragraph, surround the words that make up the paragraph with an opening
tag and closing
tag.By enclosing words in the tags and we can make characters appear bold.
The element also represents a section of text that would be presented in a visually different way (for example key words in a paragraph) although the use of the element does not imply any additional meaning.
By enclosing words in the tags and we can make characters appear italic.
The element is used to contain characters that should be superscript such as the suffixes of dates or mathematical concepts like raising a number to a power such as 2^2.
The element is used to contain characters that should be subscript. It is commonly used with foot notes or chemical formulas such as H20.
As you have already seen, the
browser will automatically show
each new paragraph or heading
on a new line. But if you wanted
to add a line break inside the
middle of a paragraph you can
use the line break tag
.
To create a break between themes — such as a change of topic in a book or a new scene in a play — you can add a horizontal rule between sections using the
tag.
The use of the element indicates that its content has strong importance. For example, the words contained in this element might be said with strong emphasis.
The element indicates emphasis that subtly changes the meaning of a sentence.
The
element is used for longer quotes that take up an entire paragraph. Note how theelement is still used inside the
element.If you use an abbreviation or an acronym, then the element can be used. A title attribute on the opening tag is used to specify the full term.
CSS allows you to create rules that specify how the content of an element should appear. For example, you can specify that the background of the page is cream, all paragraphs should appear in gray using the Arial typeface, or that all level one headings should be in a blue, italic, Times typeface.
How does CSS actually work?
When a browser displays a document, it must combine the document's content with its style information. It processes the document in a number of stages, which we've listed below. Bear in mind that this is a very simplified version of what happens when a browser loads a webpage, and that different browsers will handle the process in different ways. But this is roughly what happens.
The browser loads the HTML (e.g. receives it from the network). It converts the HTML into a DOM (Document Object Model). The DOM represents the document in the computer's memory. The DOM is explained in a bit more detail in the next section. The browser then fetches most of the resources that are linked to by the HTML document, such as embedded images and videos ... and linked CSS! JavaScript is handled a bit later on in the process, and we won't talk about it here to keep things simpler. The browser parses the fetched CSS, and sorts the different rules by their selector types into different "buckets", e.g. element, class, ID, and so on. Based on the selectors it finds, it works out which rules should be applied to which nodes in the DOM, and attaches style to them as required (this intermediate step is called a render tree). The render tree is laid out in the structure it should appear in after the rules have been applied to it. The visual display of the page is shown on the screen (this stage is called painting).
How to enable JavaScript in your browser??
Nowadays almost all web pages contain JavaScript, a scripting programming language that runs on visitor's web browser. It makes web pages functional for specific purposes and if disabled for some reason, the content or the functionality of the web page can be limited or unavailable. Here you can find instructions on how to enable (activate) JavaScript in five most commonly used browsers.
