How to fit a sticky background image and prevent overflow in css?

Finally, I figured it out!

The trick was in using grid, it took me a while but I created this master piece!

Reference link: How to create a sticky background using css?

html,
body {
  margin: 0;
  width: 100%;
  max-height: 100%;
  max-width: 100%;
}

#header {
  height: 100px;
  width: 100%;
  background: black;
}

#rest {
  display: grid;
  grid-template-columns: 1fr;
  grid-template-rows: 1fr;
  background: blue;
}

#content {
  width: 50%;
  z-index: 0;
  grid-row: 1;
  grid-column: 1;
  margin: 0 auto;
  background: yellow;
}

#sticky_back {
  width: 100%;
  height: 100vh;

  grid-row: 1;
  grid-column: 1;
  position: sticky;
  top: 0;
  background-image: url("https://images.pexels.com/photos/1591447/pexels-photo-1591447.jpeg?auto=compress&cs=tinysrgb&dpr=1&w=500");
  background-repeat: no-repeat;
  background-size: cover;
}

Fixed background image with full window stretch and fit with no repeating when scrolling?

object-fit

https://css-tricks.com/almanac/properties/o/object-fit/

it's the best choice for you that can stretch and fit 100%

.object-fit_fill { object-fit: fill }
.object-fit_contain { object-fit: contain }
.object-fit_cover { object-fit: cover }
.object-fit_none { object-fit: none }
.object-fit_scale-down { object-fit: scale-down }

https://jsfiddle.net/y3cobhp1/

& what you looking for exactly below

    .object-fit_fill { object-fit: fill }
OR
    .object-fit_cover { object-fit: cover }

Keep background image fixed during scroll using css

background-attachment: fixed;

CSS Image size, how to fill, but not stretch?

You can use the css property object-fit. ("sets how the content of a replaced element, such as an <img> or <video>, should be resized to fit its container.")

.cover {
  object-fit: cover;
  width: 50px;
  height: 100px;
}

<img src="http://i.stack.imgur.com/2OrtT.jpg" class="cover" width="242" height="363" />

CSS background-size: cover + background-attachment: fixed clipping background images

Unfortunately this is simply an artifact of how fixed positioning works in CSS and there is no way around it in pure CSS - you have to use Javascript.

The reason this happens is due to the combination of background-attachment: fixed and background-size: cover. When you specify background-attachment: fixed it essentially causes the background-image to behave as if it were a position: fixed image, meaning that it's taken out of the page flow and positioning context and becomes relative to the viewport rather than the element it's the background image of.

So whenever you use these properties together, the cover value is being calculated relative to the size of the viewport irrespective of the size of the element itself, which is why it works as expected when the element is the same size as the viewport but is cropped in unexpected ways when the element is smaller than the viewport.

To get around this you basically need to use background-attachment: scroll and bind an event listener to the scroll event in JS that manually updates the background-position relative to how far the window has been scrolled in order to simulate fixed positioning but still calculate background-size: cover relative to the container element rather than the viewport.

CSS background image - shrink to fit fixed size div

You're looking for background-size: contain (see the MDN entry), not cover. To get your example to work, you'll have to drop the background-attachment: fixed. Use background-position: center to center the background in your div.

.container{

    background: url(https://s21.postimg.org/iq2mtjaiv/bg_boardwalk.jpg) no-repeat center;

    -webkit-background-size: contain;

    -moz-background-size: contain;

    -o-background-size: contain;

    background-size: contain;

    

    height: 150px;

    width: 300px;

}

<div class="container">

</div>
