<u> HTML Tag

The <u> element was originally used to identify text that should be underlined. The element was deprecated in HTML 4.01, but in HTML5 it was redefined to represent text that should be displayed in a way that is an unarticulated but stylistically distinct from the surrounding text. For example, one proper use of the <u> element is to identify misspelled terms.

<ul> HTML Tag

The <ul> element is used to define an unordered list of items. Use an unordered list to contain <li> elements that do not need to be presented in numerical order and can be rearranged without changing the meaning of the list.

<th> HTML Tag

The <th> element is used to identify table cells that contain column header values rather than table data. A row of table heading values is created by nesting multiple <th> values in a parent <tr> element.

<title> HTML Tag

The <title> element is a required HTML element used to assign a title to an HTML document. Page titles are not displayed in the browser window, but they are used as the page name by search engines and displayed by browsers in the title bar, on the page tab, and as the page name of bookmarked webpages.

<var> HTML Tag

The <var> element is used to identify a variable in a mathematical equation or computer program. Text marked with <var> tags is displayed in an italics font style by most browsers.

The <tr> element is used to group together <th> or <td> values into a single row of table heading or data values. The <tr> element may be a direct child of a <table> element or nested within a parent <thead>, <tfoot>, or <tbody> element.

The <wbr> element is used to define a word break opportunity in a string of text. It is particularly useful when you wish to define word break opportunities in a long unbroken string of text that might otherwise break improperly.

<textarea> HTML Tag

The <textarea> element is used to create a text input area of unlimited length. By default, text in a <textarea> is rendered in a monospace or fixed-width font, and text areas are most often used within a parent <form> element.

The <td> element creates a single data cell in an HTML <table>. Data cells must be used as child elements of a parent <tr>, and the resulting group of <td> elements will be rendered as a single table row in a <table>.
