This is an example of CSS focused animation. With the CSS 3 evolved with the new behaviors of transition and animations. Now you can design the animations without using Javascript or Flash. Transitions in CSS3 gives an ability to alter the appearance and behavior of an element whenever a state change occurs, such as when it is hovered over, focused on, active, or targeted. HTML in this snippet is simple with the field class used for input. The CSS styles are defined for all the elements of the HTML. Check out the effect once you click on the input field. The input field is marked with a transform to display the animation while it is selected and deselected. You can use this as an example for other fields in case you use the CSS 3 version. Make sure the color and effect match your webpage. Source: https://codepen.io/daniandl/pen/boqyYE
