Common input element attributes

The maxlength and minlength attributes

The maxlength attribute is a form control maxlength attribute.
The minlength attribute is a form control minlength attribute.
If the input element has a maximum allowed value length, then the code-unit length of the value of the element's value attribute must be equal to or less than the element's maximum allowed value length.

The following extract shows how a messaging client's text entry could be arbitrarily restricted to a fixed number of characters, thus forcing any conversation through this medium to be terse and discouraging intelligent discourse.

<label>What are you doing? <input name=status maxlength=140></label>

Here, a password is given a minimum length:

<p><label>Username: <input name=u required></label>
<p><label>Password: <input name=p required minlength=12></label>

The size attribute

The size attribute gives the number of characters that, in a visual rendering, the user agent is to allow the user to see while editing the element's value.
The size attribute, if specified, must have a value that is a valid non-negative integer greater than zero.
e=file multiple name=att></label>

The min and max attributes

Some form controls can have explicit constraints applied limiting the allowed range of values that the user can provide. Normally, such a range would be linear and continuous. A form control can have a periodic domain, however, in which case the form control's broadest possible range is finite, and authors can specify explicit ranges within it that span the boundaries.

Specifically, the broadest range of a type=time control is midnight to midnight (24 hours), and authors can set both continuous linear ranges (such as 9pm to 11pm) and discontinuous ranges spanning midnight (such as 11pm to 1am).

The min and max attributes indicate the allowed range of values for the element.
If the element does not have a periodic domain, the max attribute's value (the maximum) must not be less than the min attribute's value (its minimum).
An element has range limitations if it has a defined minimum or a defined maximum.

The following date control limits input to dates that are before the 1980s:

<input name=bday type=date max="1979-12-31">

The following number control limits input to whole numbers greater than zero:

<input name=quantity required="" type="number" min="1" value="1">

The following time control limits input to those minutes that occur between 9pm and 6am, defaulting to midnight:

<input name="sleepStart" type=time min="21:00" max="06:00" step="60" value="00:00">

Name attribute

Definition and Usage

The <a> name attribute is not supported in HTML5. Use the id attribute instead.
The name attribute specifies the name of an anchor.
The name attribute is used to create a bookmark inside a document.
The href or the name attribute must be present in the <a> tag.


The name attribute specifies the name of an anchor:

<a name="C4">Chapter 4</a>
