The HTMLSelectElement.disabled Is a Boolean that reflects the disabled HTML attribute, which indicates whether the control is disabled. If it is disabled, it does not accept clicks. A disabled element is unusable and un-clickable.
The WindowBase64 helper contains utility methods to convert data to and from base64, a binary-to-text encoding scheme. For example it is used in data URIs.
Elements in HTML have attributes; these are additional values that configure the elements or adjust their behavior in various ways to meet the criteria the users want.
This page lists all the HTMLelements. They are grouped by function to help you find what you have in mind easily. Although this guide is written for those who are newer to coding, we intend it to be useful for anyone.
The HTML <input type="button"> element is a specific version of the <input> element used to create a clickable button with no default value. It has been superseded in HTML5 by the <button> element.
The HTML <multicol> element was an experimental element designed to allow multi-column layouts. It never got any significant traction and is not implemented in any major browsers.
The HTML<shadow> element is used as a shadow DOM insertion point. You might use it if you have created multiple shadow roots under a shadow host. It is not useful in ordinary HTML. It is used with Web Components.
Global attributes may be specified on all HTML elements, even those not specified in the standard. That means that any non-standard elements must still permit these attributes, even though using those elements means that the document is no longer HTML5-compliant. For example, HTML5-compliant browsers hide content marked as <foo hidden>...<foo>, even though <foo> is not a valid HTML element.
The accesskeyglobal attribute provides a hint for generating a keyboard shortcut for the current element. This attribute consists of a space-separated list of characters (one single Unicode code point). The browser uses the first one that exists on the computer keyboard layout.
The contenteditableglobal attribute is an enumerated attribute indicating if the element should be editable by the user. If so, the browser modifies its widget to allow editing. The attribute must take one of the following values:
The data-*global attributes form a class of attributes, called custom data attributes, allows proprietary information to be exchanged between the HTML and its DOM representation that may be used by scripts. All such custom data are available via the HTMLElement interface of the element the attribute is set on. The HTMLElement.dataset property gives access to them.
The * may be replaced by any name following the production rule of xml names with the following restrictions:
The hiddenglobal attribute is a Boolean attribute indicating that the element is not yet, or is no longer, relevant. For example, it can be used to hide elements of the page that can't be used until the login process has been completed. Browsers won't render elements with the hidden attribute set.
The itemprop global attribute is used to add properties to an item. Every HTML element can have an itemprop attribute specified, and an itemprop consists of a name-value pair. Each name-value pair is called a property, and a group of one or more properties forms an item. Property values are either a string or a URL and can be associated with a very wide range of elements including <audio>, <embed>, <iframe>, <img>, <link>, <object>, <source> , <track>, and <video>.
The titleglobal attribute contains a text representing advisory information related to the element it belongs to. Such information can typically, but not necessarily, be presented to the user as a tooltip. Here are some typical uses of this attribute:
