Please tell me a strange question. The cursor does not flash when the TAB key is moved into the input box_html/css_WEB-ITnose

tab cursor text box HTML input

Phenomenon: There are three text boxes, the cursor flashes when clicked, and moved with the TAB key, the cursor is not displayed (except for the password box, the cursor is not displayed for text type text box), although the cursor is not displayed, the input text is still in the moved text box (focus positioning should be no problem)

Reply to the discussion (solution)

If it is a simple three This text box definitely doesn’t have this problem
Let’s see if there is any abnormality in the element style?
