How to display my new created page on home page

Go to Settings tab in the admin panel. There go to Reading section and set the Contact page as the front page in the settings.
Then it will show up on your home page.

Hello @shashwatmittal thanks very much
Please am kindly asking I filled contact form 7 in my contact page but the message body back ground is in white. When ever i try to type in the message you cant see the words you are writting.
You can see the what am trying to mean on my contact form. on https://www.drndegespellcaster.com
Thanks very much

For that, you need to check your CSS style sheet.

#content, #content input, #content textarea,#content select { color: #eee; font-size: 12px; line-height: 20px; outline: none; min-height: 30px;}

This is the line that is affecting the colour of that Input. color: #eee is the reason for it being white.
