how to tell an element to change its position once it expands outside the viewport?

Question

I have a few nice description boxes attached to all buttons see picture number 0. When I change the viewport size the description box just expands outside the viewport. See in the first picture

Obviously, it is because I set the position of all my absolutely positioned description boxes the same(top:-25px right:-79px) and when a user hovers over the button on the very right it expands too far. I could change the one being on the very right but it wouldn't solve anything as I don'T know how many of these pictures will be added when the website is done.

So I want to use javascript to change the position of any description box that expands outside the viewport so that it looks like the one in the second picture.

The code I use for this setup is here:

<div id="grid-container" class="container">
  <div id="product1" class="products">
    <input id="one" type="checkbox" name="wobblers" value="one">

    <label for="one">
                            <img id="one" src="https://cdn.shopify.com/s/files/1/1557/0907/products/product-image-507865262.jpg?v=1527268422"
                                alt="rapala">
                            <button id="product1-info" class="btn btn-info">info
                                <div class="info-box" id="info-box1"></div>
                            </button>
                        </label>
  </div>
</div>

CSS:

img {
  width: 75px;
}

.info-box {
  display: none;
  width: 80px;
  height: 60px;
  background: grey;
  position: absolute;
  top: -25px;
  right: -79px;
  border-radius: 10% 10% 10% 1%;
}

#product1-info:hover #info-box1 {
  display: block;
}

.products {
  display: inline-block;
}

label {
  position: relative;
  display: inline-block;
  vertical-align: middle;
}

#grid-container {
  display: flex;
  justify-content: space-around;
  flex-wrap: wrap;
}

Thank you!

Here is the final solution:

Javascript:

const hovered = document.querySelectorAll('.product-info');
Array.prototype.forEach.call(hovered, function (item) {
    item.addEventListener("mouseover", changeElementPosition);
  });

function changeElementPosition() {
    const tooltipParent = document.querySelectorAll(".product-info");
    const tooltip = document.querySelectorAll('.info-box');
    for (let i = 0; i < tooltipParent.length; i++) {
        console.log(tooltip[i]);
        const tooltipParentRightPosition = tooltipParent[i].getBoundingClientRect().right;
        const windowWidth = document.documentElement.clientWidth;
        const tooltipInitPosition = -tooltip[i].getBoundingClientRect().width;
        if ((tooltipParentRightPosition - windowWidth) >= tooltipInitPosition) {
            tooltip[i].style.right = tooltipParentRightPosition - windowWidth + 'px';
        }
    else{
        tooltip[i].style.right = "-80px"; 
    }
    }


    window.addEventListener("resize", () => {
        const tooltipParent = document.querySelectorAll(".product-info");
        const tooltip = document.querySelectorAll('.info-box');
        for (let i = 0; i < tooltipParent.length; i++) {
            const tooltipParentRightPosition = tooltipParent[i].getBoundingClientRect().right;
            const windowWidth = document.documentElement.clientWidth;
            const tooltipInitPosition = -tooltip[i].getBoundingClientRect().width;
            if ((tooltipParentRightPosition - windowWidth) >= tooltipInitPosition) {
                tooltip[i].style.right = tooltipParentRightPosition - windowWidth + 'px';
            }
    else{
        tooltip[i].style.right = "-80px"; 
    }
        }
    });
}

CSS:

  .btn-wrapper {
    display: inline-block;
    position: relative;
  }
  .info-box{
    visibility: hidden;
    width:80px;
    height:60px;
    background:grey;
    position:absolute;
    top: -60px;
    right: -80px;
    border-radius:10% 10% 10% 1%;
  }
  .product-info:hover .info-box {
    visibility: visible;
  }

Html:

            <div id="product4" class="products">
                <input id="four" type="checkbox" name="wobblers" value="four">
                <label for="four">
                    <img id="four" src="https://cdn.shopify.com/s/files/1/1557/0907/products/product-image-507865262.jpg?v=1527268422" alt="rapala">
                    <div class="btn-wrapper">
                        <button id="product4-info" class="product-info btn btn-info">info
                            <div class="info-box" id="info-box4"></div>
                        </button>
                    </div>
                </label>
            </div>

Answer 2

function changeElementPosition() {
    const tooltipParent = document.getElementById('product1-info');
    const tooltip = document.getElementById('info-box1');
    const tooltipParentRightPosition = tooltipParent.getBoundingClientRect().right;
    const windowWidth = document.documentElement.clientWidth;
    const tooltipInitPosition = -tooltip.getBoundingClientRect().width;

    if ((tooltipParentRightPosition - windowWidth) >= tooltipInitPosition) {
        tooltip.style.right = tooltipParentRightPosition - windowWidth + 'px';
    }

    window.addEventListener("resize", () => {
        const tooltipParent = document.getElementById('product1-info');
        const tooltip = document.getElementById('info-box1');
        const tooltipParentRightPosition = oltipParent.getBoundingClientRect().right;
        const windowWidth = document.documentElement.clientWidth;
        const tooltipInitPosition = -tooltip.getBoundingClientRect().width;

        if ((tooltipParentRightPosition - windowWidth) >= tooltipInitPosition) {
            tooltip.style.right = tooltipParentRightPosition - windowWidth + 'px';
        }
    });
}




<div id="grid-container" class="container">
    <div id="product1" class="products">
        <label for="one">
            <input id="one" type="checkbox" name="wobblers" value="one">
        </label>
        <img>
        <div class="btn-wrapper">
            <button id="product1-info" class="btn btn-info">info</button>
            <div class="info-box" id="info-box1"></div>
        </div>
    </div>
</div>

And several changes in CSS

.btn-wrapper {
    display: inline-block;
    position: relative;
}
.info-box {
    visibility: hidden;
    width: 80px;
    height: 60px;
    background: grey;
    position: absolute;
    top: -60px;
    right: -80px;
    border-radius: 10% 10% 10% 1%;
}

#product1-info:hover + #info-box1 {
    visibility: visible;
}

Hope it's help you)
