HTML input placeholder work as a hint to a given element which helps to identify the required value of the given input field. This can be used for input textfield or textarea before the user is actually entering their input. It selects the value from the respective selector element included as a placeholder text and displayed it as a suggestion when the user enters the input into the input field. Placing placeholders into the input field makes it the user easy to enter the required value into the given input field. So it minimizes the user’s efforts. Basically, the placeholder is in lighter grey color, but we can also able to change its color by using some CSS properties.

Syntax:

Let’s see the syntax for the placeholder, how exactly it is going to be used in the input field.

<element placeholder="placeholder_text">

Copy after login

The attribute for and element is placeholder. The placeholder is treated as some hint to the user to enter actual input value into the input field.</p> <p>The placeholder can be styled by using some CSS code s follows:</p> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false">::placeholder{ //CSS code; }</pre><div class="contentsignin">Copy after login</div></div> <p>The placeholder can be implemented by using features like contrast ratio which is describing that your placeholder color is lighter than the background of the input field, usability defines the text you are using as a placeholder must disappear whenever entering input in the input field.</p> <p>By defining placeholders besides the input field is also treated as the best way of using a placeholder for the input field.</p> <p>Those input fields are going to be used with some pseudo-classes like enabled, disabled, read-only, read-write, placeholder-shown, default, checked, indeterminate, valid, invalid, in-range, out-of-range, required, optional, blank, and more other classes also.</p> <p>Like classes there are many attributes also going to be used like max, maxlength, min, minlength, pattern, required, step, type, etc.</p> <p>Let’s see how placeholder going to be used with the input text:</p> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"><input type="text " placeholder="placeholder-text"></pre><div class="contentsignin">Copy after login</div></div> <p>This syntax is for simple input textfield, so you will help the user to add proper input into the input field by using the placeholder attribute. Placeholder–text is nothing but a suggestion about what actually the user is going to enter in this input field.</p> <p>One another thing where we are using placeholder is input textarea. In this input field, we can suggest what exactly one can give as an input by using placeholder so it will be helpful for both people who are taking input for appropriate input value as well as for user who is entering input for better user experience.</p> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"><input type="textarea" placeholder="placeholder-text"></pre><div class="contentsignin">Copy after login</div></div> <p>There are two different things in the placeholder, one is :placeholder-shown which gives the meaning that selection of input is done when it’s through placeholder text which is available in the input field whereas another one is::placeholder which is used to give styles to the placeholder.</p> <p>Placeholder doesn’t work as a title or label attribute or neither it’s treated as a replacement for both of them.</p> <p>One can change the style of placeholder to display placeholder same in any browser, for this scenario we have to apply CSS code for the specific browser so it will display the same thing in each browser.</p> <h3 id="Examples-of-HTML-Input-Placeholder">Examples of HTML Input Placeholder</h3> <p>Here are the following examples mentioned below.</p> <h4 id="Example">Example #1</h4> <p>In this example we are going to create one Login form and one Registration form in which we are using a placeholder for all input field so HTML code and output for this is as follows:</p> <p><strong>Code:</strong></p> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"><!DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width, initial-scale=1"> <style> .container { padding: 2px 12px;
