Input[type= ' text ' The text box cursor height changes greatly when there is input and is empty.

First, let's take a look at the cause of the problem: the Chrome browser sets the cursor height to the line-height value of the cursor height =input when there is no content, and when there is content, the cursor moves from the top of input to the bottom of the text.

OK, now that we know the reason, we will go to some measures accordingly. There are two ways to do it:.

Method 1: Set the value of Line-height to match the font size, if the height is not reached, use padding to support;

Method 2: For Chrome does not set Line-height, it will automatically center text, ie hack set the value of Line-height to ensure that the text is vertically centered; Note that if you have set line-height equivalents in the Reset style file, Please make a line-height reset, you can use the Line-height:normal.
