HTML documents use tags to instruct browsers on how to display text. The code tag identifies text as computer code and can be styled using attributes like id, class, and style. Optional events like onclick can also be included. Browsers have default styles, but formatting may vary without attributes.
All HTML documents consist of text only. These documents include both the text to be displayed and instructions on how it should be displayed by the Internet browser. The instructions are given by the tags that are included in the text document. The HTML code tag is one such instruction and identifies the text as computer code.
When using most tags, you should include an opening and closing tag so the browser knows where to use the instructions. The code tag is one of the tags that must have an opening and closing tag. When used, it takes the following format: hello. If this instruction were read by the browser, it would change the way the word hello is formatted so that it is differentiated from other text on the page. Usually, when the code tag is used, a browser changes the font of the words surrounded by the tags to monospaced or something similar to that.
This tag has no specific attributes or characteristics that are unique. When writing an HTML document, the format of any computer code can be specified using other general attributes. If style sheets are used for document formatting, id, class and style can be used to indicate how the text is styled. Other attributes that can be included with the code tag are title, lang, and dir: title gives a specific title to the tag, lang specifies the language, and dir gives the direction of the text, left-to-right or right-to-left.
Events are actions taken by a web user, such as clicking or double-clicking something on the page. These events can be encoded within the HTML document and can also be included in the code tag. Optional events that can be used as attributes for the code tag include onclick, ondblclick, onkeydown, onkeypress, onkeyup, onmousedown, onmouseup, onmouseover, and onmouseout.
Most browsers have a default style to use when encountering the code tag within an HTML document. Using attributes with this tag is completely optional, so you don’t need to specify any. If the attributes are not included, the browser will just use the default. It is important to note that not all browsers will display the text of the code in the same way. Browsers will display code text differently than the text surrounding the page, but each browser may not format code text the same way if the attributes and styles are not included in the code tag.
