You know that blue border that when you write something inside of an input. How do i make dissapear

Answer 1

In addition to what Potato Squad said, focus styling is very important in making your site accessible for keyboard users. Therefore it is not advisable for a focusable element to be without focus styling.

After removing the border, you should consider adding another form of styling, may be change the background.

textarea:focus, input:focus {
outline: none;
border: none;
background-color: #eec;
}

Answer 2

Style:
textarea:focus, input:focus{ outline: none; }
