    Was previously used to specify the alignment and placement of an image relative to the surrounding text. It has been deprecated and should not be used.

    The frame attribute was used to define the visible borders of a table. It is now deprecated and should no longer be used.

    Previously used to add horizontal space on both side of an image. It is now deprecated.
  • <input language="">

    Was used to indicate the scripting language used for events triggered by the input.
  • <thead> HTML Tag

    The <thead> element is used to identify one or more rows of a table that contain column labels rather than table data.

    Identifies an image as a server-side image map. When the containing anchor link is clicked, the coordinates of the mouse will be included in the request.
  • <img usemap="">

    Specifies a client-side image map to be used with the image.

  • <label for="">

    Specifies the ID of the associated form field element.
  • <img nosave>

    Was intended to prevent users from downloading an image. Was never a part of the HTML specification, and not widely implemented.
  • <legend> HTML Tag

    The <legend> element is used to add a caption to a group of related form <input> elements that have been grouped together into a <fieldset>.
  • <img dynsrc="">

    An early failed attempt to include native video playback in HTML.
  • <legend align="">

    Was used to specify the placement of the legend element. Deprecated. Use CSS instead.
  • <img controls>

    Toggled media player controls when used in conjunction with the dynsrc attribute. Both attributes are now deprecated.
  • <li> HTML Tag

    The <li> element defines a list item that is part of an ordered and unordered list of items.
  • <img start="">

    Was used in conjunction with the dynsrc attribute to add a video that would load in supported browsers in the place of the image that would otherwise be displayed.

    Specifies the name of an input element. The name and value of each input element are included in the HTTP request when the form is submitted.
  • <span> HTML Tag

    The <span> element is the inline equivalent to the block-level <div> element. It is used to select inline content for purely stylistic purposes.
  • <style type="">

    Identifies the type of media contained within a <style> element. However, the only supported value is text/css, so the attribute is not needed.
  • <area> HTML Tag

    The <area> element is used as a child of a <map> element to define clickable a region on an image map. Different regions of an image map can be hyperlinked to different locations by nesting multiple <area> elements in a single <map> element.
