Image not constrained by parent div height, only width

Question

my gatsby image is correctly constrained by width of the parent div, but not by the height property.

Width of image will not exceed the parent div (pink border):

However, if i increase browser size, the height of image goes beyond parent div (pink border):

Below is the code - how can I fix this? Thanks in advance!

    <div 
  style={{
    display: `flex`,
    justifyContent: `flex-start`,
    borderStyle: `solid`,
    borderColor: `blue`,
    height:`70vh`,
    width:`100%`,
    marginTop: `3rem`
}}>
  <div className="imageContainer" 
    style={{
      width:`50%`,
      height:`100%`,
      borderStyle: `solid`,
      borderColor: `pink`,
  }}>
    <StaticImage
      src="../images/about.jpg"
      layout="constrained"
      width={1200}
      height={1100}
      quality={90}
      formats={["auto", "webp", "avif"]}
      alt="home image"
      style={{ 
        marginBottom: 0,
      }}
    />
  </div>

</div>

Answer 1

So do you want the image inside the pink border always follow the width and the height of the pink border div?

If yes, I think you can achieve it with this css below, add it to StaticImage className props.

.static-image {
  height: 100%;
  width: 100%;
  object-fit: cover;
}
