Flexbox, @Media queries

Hey, for the image to match the color, I did something like this, I hope that helps, size might not fit your solution but you can adapt it depending on your own code:

<div class="image-container">
img class="main-image" src="images/image-header-mobile.jpg" alt="">
</div>

.image-container {
  display: inherit;
  position: relative;
  width: 100%;
  border-radius: 0 10px 10px 0;
  background-color: hsl(277, 64%, 61%);
}
.main-image {
  width: 100%;
  height: 100%;
  position: relative;
  background-size: cover;
  border-radius: 0 10px 10px 0;
  mix-blend-mode: multiply;
  opacity: 0.75;
}

IF THIS WAS HELPFUL PLEASE MARK IT AS HELPFUL 🤩

Hi John, how are you? I really liked the result of your project, but I have some tips that I think you will enjoy:

To get closer to the photo overlay effect, you'd better use mix-blend-mode. All you need is the div under the image with this background color: hsl(277, 64%, 61%); and position mix-blend-mode: multiply and opacity: 80% on the image or apply image to activate the overlay by blending the image with the div's color. See the code below:

img {
    mix-blend mode: multiply;
    opacity: 80%;
}

You can read this content which is explaining these effects with mix-blend-mode: click here

To align some content in the center of the screen, always prefer to use display: flex; it will make the layout more responsive!

body {
    margin: 0;
    padding: 0;
    display: flex;
    align-items: center;
    flex-direction: column;
    justify-content: center;
    min-height: 100vh;
}

The rest is great!

I hope it helps... 👍
