I have chat and I need to scroll all content to bottom. I want to use justify-content: flex-end and to have vertical scrollbar.
.session-textchat { height: 320px; background: #fff; display: -webkit-flex; display: flex; -webkit-align-items: flex-end; align-items: flex-end; -webkit-justify-content: space-between; justify-content: space-between; -webkit-flex-direction: column; flex-direction: column; } .session-textchat .past-messages { width: 100%; max-width: 980px; margin: 0 auto; height: 83.92%; overflow-y: auto; padding: 30px 0 0; display: -webkit-flex; display: flex; -webkit-align-items: flex-end; align-items: flex-end; -webkit-justify-content: flex-end; justify-content: flex-end; -webkit-flex-direction: column; flex-direction: column; } .session-textchat .past-messages .receiver, .session-textchat .past-messages .sender { width: 100%; min-height: 47px; margin: 0 0 20px; display: -webkit-flex; display: flex; -webkit-flex-direction: row; flex-direction: row; } .session-textchat .past-messages .receiver .message, .session-textchat .past-messages .sender .message { position: relative; padding: 17px; -moz-border-radius: 4px; -webkit-border-radius: 4px; border-radius: 4px; } .session-textchat .past-messages .receiver { text-align: left; -webkit-justify-content: flex-start; justify-content: flex-start; } .session-textchat .past-messages .receiver .message { background: #f4f4f4; color: #535353; } .session-textchat .past-messages .sender { text-align: right; -webkit-justify-content: flex-end; justify-content: flex-end; } .session-textchat .past-messages .sender .message { background: url('../img/rgbapng/0050ff26.png'); background: rgba(0, 80, 255, 0.15); color: #0050ff; }<div> <div> <div> <span> Good afternoon David.

I just had to face this issue myself and, after concluding it is a bug, I came up with a workaround.
In summary, don't use justify-content: flex-end but rather put a margin-top: auto on the first child. Unlike flex-end this doesn't break the scrollbar functionality, and it bottom-aligns the contents when they're not overflowing the container.
Example based on @SrdjanDejanovic's fiddle is at
In case the example isn't available, here's the relevant CSS:
#container { overflow-y: auto; display: flex; flex-flow: column nowrap; /* justify-content: flex-end; DO NOT USE: breaks scrolling */ } #container > :first-child { margin-top: auto !important; /* use !important to prevent breakage from child margin settings */ } An alternative workaround that I believe I've also used is to add an extra container for the scrollbar. Use the flex-end on the inner container and have the outer container handle the scrolling. I generally dislike workarounds that require adding dummy elements though, so I prefer my CSS-only solution above.
5Probably you've already solved this, but I faced this problem too and found a solution by trial and error, so I'm going to share it.
Having parent container's display set to flex display: flex and child's items align to flex-end align-items: flex-end will prevent overflow-y: auto to work.
Instead, you can leave you can use next CSS properties for your parent container (in your case session-textchat):
display: flex; flex-direction: column-reverse; /* 'column' for start, 'column-reverse' for end */ overflow-y: scroll; /* or overflow-y: auto ... */ This will make your child div appear on the bottom of parent container (it will act like flex-end) and enable vertical scroll if content height is bigger than parent container.
I made a little jsfiddle for you if this sounds confusing:
In jsfiddle you can see header part, content part and footer. Container has fixed height and each part takes required height to fill the container. Content part _b__content will be scrollable if its content is taller than _b__content's height.
I hope this will help someone. Cheers.
6Also There is also another Solution
Remove the justify-content and add flex: 1 1 auto; property to the first element(create an empty div)
Old
HTML
<div> <div>Item 1</div> <div>Item 2</div> <div>Item 3</div> </div> CSS
.content-reversed { display: flex; flex-direction: column; justify-content: flex-end; } New
HTML
<div> <div></div> //add this dummy div <div>Item 1</div> <div>Item 2</div> <div>Item 3</div> </div> CSS
.content-reversed { display: flex; flex-direction: column; } .content-reversed .fix { flex: 1 1 auto; } It seems to be a common bug among the browsers.
You should distribute your style onto 2 containers: the outer will be scrolled, and the inner will be a flex container. Also, you need some js to keep your message list scrolled to bottom while adding new messages.
Here is an example of code:
markup:
<div id='outer'> <div id='inner-scroll'> <div id='inner-flex'> <div class='flex-item'>Item 1</div> <div class='flex-item'>Item 2</div> ... </div> </div> style:
#inner-scroll { height: 100%; overflow: auto; } #inner-flex { display: flex; flex-direction: column; justify-content: flex-end; min-height: 100%; } .flex-item { /*nothing*/ } JS:
function messagePushCallback() { var scrollable=document.getElementById('inner-scroll'); scrollable.scrollTo(0, scrollable.scrollHeight-scrollable.clientHeight); } // for an example chat.onMessagePush(messagePushCallback); window.addEventListener('load', messagePushCallback); In JS, scrollable.scrollHeight shows the whole height of the element, including the space beyond its visible part, while scrollable.clientHeight is for the height of the visible part.
You have to turn .session-textchat into a flex column then margin-top: auto on .past-messages to send it to the bottom. Then play with overflow-y: scroll and some jQuery:
function updateScroll() { $("#chat").animate({ scrollTop: $('#chat').prop("scrollHeight")}, 1000); } updateScroll(); $("#send_button").on('click', updateScroll);.session-textchat { display: flex; flex-direction: column; height: 300px; margin-bottom: 30px; background: #fff; overflow-y: scroll; } .session-textchat .past-messages { margin-top: auto; width: 100%; max-width: 980px; } .session-textchat .past-messages .receiver, .session-textchat .past-messages .sender { width: 100%; min-height: 47px; margin: 0 0 20px 0; } .session-textchat .past-messages .receiver .message, .session-textchat .past-messages .sender .message { position: relative; padding: 15px; -moz-border-radius: 4px; -webkit-border-radius: 4px; border-radius: 4px; } .session-textchat .past-messages .receiver { text-align: left; } .session-textchat .past-messages .receiver .message { background: #f4f4f4; color: #535353; } .session-textchat .past-messages .sender { text-align: right; } .session-textchat .past-messages .sender .message { background: url("../img/rgbapng/0050ff26.png"); background: rgba(0, 80, 255, 0.15); color: #0050ff; }<script src=""></script> <link href="" rel="stylesheet" /> <div> <div> <div> <div> <span> Good afternoon David.

This solution worked for me:
display: flex; flex-direction: row-reverse; justify-content: flex-start;
