title: How to set the size of button in HTML
body: <p>I have some buttons on my pure HTML/JS page.
  When the page is opened in browser, the button size is normal.
  But on refresh/reloading page, the button size is reduced.
  In fact, I have not set the button text value. The button's text is blank.
  How should I set the size of my button in HTML irrespective to the size of the text?</p>
