How to align-items: center AND align-self: stretch? - html

Question

I have an element I'd like to be (cross-axis) centered but also 'grow' to a nominal size even with too-little content, BUT ALSO 'shrink' when the width of the page becomes smaller than 350px wide.
HTML
<div class="parent">
<div class="child">
Some content
</div>
</div>
SCSS
.parent {
display: flex;
flex-direction: column;
align-items: center;
.child {
max-width: 350px;
align-self: stretch;
}
}
Adding align-self: stretch; to .child does the job of making it 350px wide, but it seems to negate the align-items: center; in .parent
Is there a way to do this in CSS that I'm missing? Please note that the element can't just be 350px wide all the time - it must also respond to horizontal page resizing as it does in the example fiddle.

I think you should use justify-content to h-align child to center.
Please note, when you apply display: flex property to parent, you should apply flex property to child.
.parent {
background: yellow;
display: flex;
flex-direction: column;
align-items: center;
}
.parent .child {
background: black;
color: white;
text-align: center;
flex: 1 1 auto;
width: 100%;
max-width: 350px;
}
<div class="parent">
<div class="child">
I should be 350px wide
<br> and centered in the yellow
<br> unless the page gets smaller,
<br> in which case I should have
<br> 10px padding on either side.
</div>
</div>
Please see the result here, hope this is what you mean: https://jsfiddle.net/1uqpxn8L/11/

You can do something like this.
HTML
<div class="parent">
<div class="child">
Some content
</div>
</div>
SCSS
.parent {
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
padding: 10px;
.child {
width: 350px;
#media(max-width: 350px) {
width: 100%;
}
}
}
.parent {
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
padding: 10px;
background-color: red;
}
.child {
width: 350px;
background-color: yellow;
}
#media(max-width: 350px) {
.child { width: 100%; }
}
<div class="parent">
<div class="child">
Some content
</div>
</div>
So whats happening is I'm using a media query to change the width of the child depending on the width of the browser.

You just need to remove the flex-direction property. Then it's working as you expected. But there will be a problem if you want to display children elements as column manner. The shrinking problem occurs with the flex-direction property or flex-flow:column values as I checked.
