HTML <input> height attribute
Definition and usage
height
The attribute specifies the height of the <input> element.
Note:height
The attribute is only related to <input type="image"> Use together.
Tip:It is a good habit to specify the height and width of the image. If these attributes are set, space for the image is reserved when the page is loaded. Without these attributes, the browser cannot understand the size of the image and therefore cannot reserve appropriate space for it. In this case, the page layout changes when the page and the image are loaded.
Example
Definition of the image as a submit button with height and width attributes:
<form action="/action_page.php"> <label for="fname">名字:</label> <input type="text" id="fname" name="fname"><br><br> <label for="lname">Nachname:</label> <input type="text" id="lname" name="lname"><br><br> <input type="image" src="img_submit.gif" alt="Submit" width="48" height="48"> </form>
