H1 gives me a white background color on the text-CodePudding

I'm trying to add a header on top of this image with a gradient that I've made but it gives me a weird white background as such https://i.stack.imgur.com/ppuJq.png I want the text on top of the image to have a transparent background. Made the navbar black so its easier to see but anyway, how do I remove it? I am aware that the js script is unfinished if that has anything to do with it.

here is my code

/*

* {
  margin: 0;
}

.WelcomeMenu h1 {
  font-size: 50px;

}

.img-gradient {
  position: absolute;
  width: 100%;
  height: 85vh;
}

  top: 0;
  width: 100%;
  height: 85vh;
  background: linear-gradient(rgba(0, 0, 0, 0.85), rgba(0, 0, 0, 0.85));

CodePudding user response：

It's because of the background color on body tag and the transparent background on .WelcomeMenu. Ways to fix (Only one of them):

Add a background color to .WelcomeMenu
Have a parent element and set the background color to black
Make the background color of body black

/*

CodePudding user response：

The image that you are using is a background image! so for a better solution you can make it the background of the div.WelcomeMenu.

The white color is the background of the page (by default - which is blank white page). and the order of the elements is:

Navbar - black background
h1 - the background of the page 
img - the image itself

that means, the h1 is between the two elements.

In case you still want the elements as they are, you can simply add:

.WelcomeMenu {
   position: relative;
}

.WelcomeMenu h1 {
   color: #ffffff;
   font-size: 50px;
   position: absolute;
   top: 100px; (change it as you wish)
   left: 100px; (change it as you wish)
}

The Code:

/*
CSS for the page:
*/

* {
  margin: 0;
}

.WelcomeMenu {
  position: relative;
  height: 85vh;
  width: 100%;

  background-repeat:  no-repeat;
  background-position: center;
  background-size: cover;
