Resize components

[Tsiangana]

First, I chose to remove the inline css that was in the html and transfer it to the external css in order to make the html code simpler and easier to interpret.
Secondly, I chose to place the button toggle inside the h1 so I remove the position absolute property and applied a display flex and an align item center and a justify content space betwen so it is easier to adjust the screen, they always have the same size
And thirdly, the main thing that irritated me the most, when reducing the screen size the button numbers were not clearly visible, so I applied a media screen so that when the screen reached a size of 700px the font-size of the button numbers were enlarged, and to improve this I applied a cursor poiter to the buttons in order to make them more realistic
