Html link http or https

: The Anchor element

The HTML element (or anchor element), with its href attribute, creates a hyperlink to web pages, files, email addresses, locations in the same page, or anything else a URL can address.

Attributes

This element’s attributes include the global attributes.

Causes the browser to treat the linked URL as a download. Can be used with or without a filename value:

  • Without a value, the browser will suggest a filename/extension, generated from various sources:
    • The Content-Disposition HTTP header
    • The final segment in the URL path
    • The media type (from the Content-Type header, the start of a data: URL, or Blob.type for a blob: URL)
    • download only works for same-origin URLs, or the blob: and data: schemes.
    • How browsers treat downloads varies by browser, user settings, and other factors. The user may be prompted before a download starts, or the file may be saved automatically, or it may open automatically, either in an external application or in the browser itself.
    • If the Content-Disposition header has different information from the download attribute, resulting behavior may differ:
      • If the header specifies a filename , it takes priority over a filename specified in the download attribute.
      • If the header specifies a disposition of inline , Chrome and Firefox prioritize the attribute and treat it as a download. Old Firefox versions (before 82) prioritize the header and will display the content inline.

      The URL that the hyperlink points to. Links are not restricted to HTTP-based URLs — they can use any URL scheme supported by browsers:

      • Sections of a page with document fragments
      • Specific text portions with text fragments
      • Pieces of media files with media fragments
      • Telephone numbers with tel: URLs
      • Email addresses with mailto: URLs
      • While web browsers may not support other URL schemes, websites can with registerProtocolHandler()

      Hints at the human language of the linked URL. No built-in functionality. Allowed values are the same as the global lang attribute.

      A space-separated list of URLs. When the link is followed, the browser will send POST requests with the body PING to the URLs. Typically for tracking.

      How much of the referrer to send when following the link.

      • no-referrer : The Referer header will not be sent.
      • no-referrer-when-downgrade : The Referer header will not be sent to origins without TLS (HTTPS).
      • origin : The sent referrer will be limited to the origin of the referring page: its scheme, host, and port.
      • origin-when-cross-origin : The referrer sent to other origins will be limited to the scheme, the host, and the port. Navigations on the same origin will still include the path.
      • same-origin : A referrer will be sent for same origin, but cross-origin requests will contain no referrer information.
      • strict-origin : Only send the origin of the document as the referrer when the protocol security level stays the same (HTTPS→HTTPS), but don’t send it to a less secure destination (HTTPS→HTTP).
      • strict-origin-when-cross-origin (default): Send a full URL when performing a same-origin request, only send the origin when the protocol security level stays the same (HTTPS→HTTPS), and send no header to a less secure destination (HTTPS→HTTP).
      • unsafe-url : The referrer will include the origin and the path (but not the fragment, password, or username). This value is unsafe, because it leaks origins and paths from TLS-protected resources to insecure origins.

      The relationship of the linked URL as space-separated link types.

      Where to display the linked URL, as the name for a browsing context (a tab, window, or ). The following keywords have special meanings for where to load the URL:

      • _self : the current browsing context. (Default)
      • _blank : usually a new tab, but users can configure browsers to open a new window instead.
      • _parent : the parent browsing context of the current one. If no parent, behaves as _self .
      • _top : the topmost browsing context (the «highest» context that’s an ancestor of the current one). If no ancestors, behaves as _self .

      Note: Setting target=»_blank» on elements implicitly provides the same rel behavior as setting rel=»noopener» which does not set window.opener .

      Hints at the linked URL’s format with a MIME type. No built-in functionality.

      Deprecated attributes

      Hinted at the character encoding of the linked URL.

      Note: This attribute is deprecated and should not be used by authors. Use the HTTP Content-Type header on the linked URL.

      Used with the shape attribute. A comma-separated list of coordinates.

      Was required to define a possible target location in a page. In HTML 4.01, id and name could both be used on , as long as they had identical values.

      Note: Use the global attribute id instead.

      Specified a reverse link; the opposite of the rel attribute. Deprecated for being very confusing.

      The shape of the hyperlink’s region in an image map.

      In this tutorial you will learn how to create links to other pages in HTML.

      A link or hyperlink is a connection from one web resource to another. Links allow users to move seamlessly from one page to another, on any server anywhere in the world.

      A link has two ends, called anchors. The link starts at the source anchor and points to the destination anchor, which may be any web resource, for example, an image, an audio or video clip, a PDF file, an HTML document or an element within the document itself, and so on.

      By default, links will appear as follows in most of the browsers:

      • An unvisited link is underlined and blue.
      • A visited link is underlined and purple.
      • An active link is underlined and red.

      However, you can overwrite this using CSS. Learn more about styling links.

      Links are specified in HTML using the tag.

      A link or hyperlink could be a word, group of words, or image.

      Anything between the opening tag and the closing tag becomes the part of the link that the user sees and clicks in a browser. Here are some examples of the links:

      Example

      The href attribute specifies the target of the link. Its value can be an absolute or relative URL.

      An absolute URL is the URL that includes every part of the URL format, such as protocol, host name, and path of the document, e.g., https://www.google.com/ , https://www.example.com/form.php , etc. While, relative URLs are page-relative paths, e.g., contact.html , images/smiley.png , and so on. A relative URL never includes the http:// or https:// prefix.

      The target attribute tells the browser where to open the linked document. There are four defined targets, and each target name starts with an underscore( _ ) character:

      • _blank — Opens the linked document in a new window or tab.
      • _parent — Opens the linked document in the parent window.
      • _self — Opens the linked document in the same window or tab as the source document. This is the default, hence it is not necessary to explicitly specify this value.
      • _top — Opens the linked document in the full browser window.

      Try out the following example to understand how the link’s target basically works:

      Example

      Tip: If your web page is placed inside an iframe, you can use the target=»_top» on the links to break out of the iframe and show the target page in full browser window.

      Creating Bookmark Anchors

      You can also create bookmark anchors to allow users to jump to a specific section of a web page. Bookmarks are especially helpful if you have a very long web page.

      Creating bookmarks is a two-step process: first add the id attribute on the element where you want to jump, then use that id attribute value preceded by the hash sign ( # ) as the value of the href attribute of the tag, as shown in the following example:

      Example

      Jump to Section A 

      Section A

      Lorem ipsum dolor sit amet, consectetur adipiscing elit.
