adding dark mode and a standard logo and about section

[arpitkumar008]

By adding a Dark Mode switch in your website , you can improve visual comfort, enhance energy efficiency, increase readability, provide an appealing aesthetic, offer customization options, and promote visual health. and i will design a proper logo and if you agree with it then i will add it . and the about section will display the content rather then using github
