What Are HTML Columns?

Hypertext Markup Language or Hypertext Markup Language (an application under the standard universal markup language) HTML (HyperText Mark-up Language) is a standard language for making web pages. Obstacles to information exchange between different computers.

HTML files can be multiple

HTML tags contain several key parts, including tags (and their attributes), character-based data types, character references, and entity references. HTML tags are the most common and usually appear in pairs, such as <h1> and </ h1>. Of these tags that appear in pairs, the first tag is the start tag and the second tag is the end tag. The content of the element is between the two tags. Some tags have no content and are empty elements, such as <img>.

Another important part of HTML is the document type declaration, which triggers standard mode rendering.

The following is a classic]

Main article: HTML attributes

Most element attributes appear in pairs in the form of "name-value", separated by "=" and written after the opening tag element name. Values are usually surrounded by single or double quotes. Some values contain specific characters. You can remove quotes in HTML (XHTML does not work). Unquoted attribute values are considered unsafe. Some attributes do not need to appear in pairs, and only exist in the opening tag to affect elements, such as the ismap attribute of the img element.

Many elements share some common attributes:

• The id attribute provides a unique identifier for the element within the entire document. It is used to identify elements so that style sheets can change their presentation attributes, and scripts can change, display, or delete their content or formatting. For URLs Tim adds to a page, it provides a globally unique identifier for the element, usually a subsection of the page. For example, the ID "attribute" for the https://en.wikipedia.org/wiki/HTML# attribute

• The class attribute provides a way to classify similar elements. Often used for semantic or formatting. For example, an HTML document may specify the class <class = "tag"> to indicate that all elements with values of this type are subordinate to the main text of the document. After formatting, such elements may clump together and appear as page footnotes without appearing in the HTML code. Class attributes are also used

  Main article: Semantic HTML

  Semantic HTML is a way of writing HTML that emphasizes the meaning of encoded information above its format (look). HTML has included semantic markup since its inception, but also includes markup tags such as <font>, <i>, and <center> tags. There are also some semantically neutral span and dl tags. Since the late 1990s

  HTML documents are distributed in the same way as other computer files. However, they most often pass through

  Let's see an example of an HTML file. Open your favorite web browser, type the relevant URL into the address input box of the browser, and enter the Active Server Pages network (your computer should be connected to the Internet). When this web page is displayed on the screen, select the View Source command from the menu bar of the web browser. A new window will pop up on the screen and display some weird text. The text you see is an HTML file.
