The placeholder selector is a pseudo-element used to create placeholder text designs in CSS. This selector can modify the text colors and style.
The pseudo-elements are initially employed to style the first line with CSS properties. Placeholder pseudo-elements can be included based on the web browser's specifications. Typically, browsers render the placeholder text in a faint or light grey shade by default. CSS text properties can be utilized to customize the appearance of the inline placeholder text.
Syntax

::placeholder {
/* CSS properties */
color: navy;
}
Or
input::placeholder {
/* CSS properties */
color: navy;
}
Supported Styles Properties
