This is another example of a sign in form with a Forgot Password option, designed using CSS, HTML, and Bootstrap framework 4. The background image and Bootstrap styles have been imported to the code with their URLs. The form consists of two other internal forms; the sign-in form and the Forgot Password form. The body of the form is given the styles of font color as #edf3ff, background color as #c8c8c8, and font style as 600 16px/18px 'Open Sans',sans-serif. The text-transform style for the titles of the two forms is set as uppercase to automatically convert the text to uppercase. The tabs are given a font size of 22px, and a transform effect as rotateY(180deg), to create the rotating effect. The active tab takes the font color of #fff and the border color of #1161ee. The 'Submit' and 'Reset password' buttons are given a background color of #1161ee.
