Append Required Field Deed For Free

Asterisk (*) next to a form control's label usually indicates it as "required". Oftentimes, this asterisk's purpose is then explained somewhere else on the page. Many users (especially screen reader users) may be confused with that, so be sure to make this information is easily accessible.

To make a select mandatory with HTML, use the required attribute. With the required attribute, the user must select a value before submitting the form; if the user refuses to select a value, then the form won't submit.

The :required selector selects form elements which are required. Form elements with a required attribute are defined as required. Note: The :required selector only applies to the form elements: input, select and textarea. Tip: Use the :optional selector to select form elements which are optional.

Use ::after to create a pseudo-element containing an asterisk * to mark one or more input fields as required with an asterisk in HTML and CSS. ::after can be used to add an asterisk * after the label text of each input to indicate that the field is required.

The <label> tag comes in pairs. The content is written between the opening (<label>) and closing (</label>) tags. There are two ways to associate a text label and the form to which it belongs: Set the identifier (id) inside the <input> element and specify its name as a for attribute for the <label> tag.

We can easily use the required attribute with the <select> element as shown in the following syntax: <select required>

Const input = document. getElementById('first_name'); // ? Set required attribute input. setAttribute('required', ''); // ? Remove required attribute input.

Fields can be marked as mandatory, meaning they must contain a value before the record can be saved. Mandatory fields are marked with a field status indicator before the label.

When you make a field required, people must enter an answer to the field in order to submit their entry. When someone tries to submit an entry without filling out a required field, we highlight the problematic fields and display an error message to let them know the field is required.
