A mobile terminal comprising: a touch screen; and a controller configured to: display a representative web page or a plurality of web pages on the touch screen, display the plurality of web pages in a parallel and layered state in response to receiving a touch and drag input on an identifier area of the representative web page; and sequentially slide the plurality of web pages according to the drag input in a layered sequence of the plurality of web pages so that a top page of the plurality of web pages moves in a direction of the drag input and each of the plurality of web pages under the top page is revealed to increase an amount of the web pages that is displayed, characterized in that the representative web page is one among the plurality of web pages and each of the plurality of web pages includes a top side, a bottom side, a left side and a right side; the controller is configured to: set a separation gap between one of the plurality of web pages and an adjacent web page overlapping the one web page according to a prescribed input on the one web page to increase the separation gap, the separation gap being increased to increase an amount of the one web page that is displayed while at least a portion of each of the plurality of web pages is displayed, wherein the separation gap is a distance between the top side of the one web page and the top side of the adjacent web page, adjust the separation gap by enlarging or narrowing the separation gap between the one web page and the adjacent web pages according to a second touch input, change the width of the bottom side of the web pages to be smaller than the width of the top side of the web pages when the prescribed input is received, and return the changed web pages to a previous state when the prescribed input is terminated, wherein the previous state indicates the width of the bottom side of the web pages is same to the width of the top side of the web pages. a touch screen;
