What is placeholder meaning?

A placeholder is a temporary element that is used to reserve a space for content that will be added later. In graphic design, placeholders are often used to represent images, text, or other elements that are not yet available. They can be created using various tools such as placeholder images or dummy text. In web development, placeholders are often used in forms to indicate the type of data that is expected to be entered. Placeholders are useful for designers and developers to visualize the overall layout of a design or webpage and to ensure that there is enough space for all elements. Placeholders can also be used to communicate to other team members or clients what content is still missing and needs to be added.
