What Does Max-Width: 0Px Do

Why does this behave the way it does with max-width: 0?

Note: It's not just max-width:0, it's any width less than the text content's width.

The mixture of display: table-cell, max-width, and width:100% make an interesting situation that the specifications don't explicitly cover. However, by making some observations and thinking, we can understand why we have the same behavior across all major browsers.

max-width:0 tries to make the element width 0, of course, meaning that everything should be overflow. However, the combination of display: table-cell and width:100%, as seen in the linked demo, override that command for the div (maybe for the same reason why max-width does not apply to table rows) for the most part. As such, the element displays itself like it would without the max-width:0 until the width of the div is no longer large enough to contain all of the text content.

A thing to note before we continue is that the text itself by default has a width that is set by the characters inside of it. It's kind of a child element of the parent div, though there are no tags.

This innate width of the text content is the reason why max-width:0 is needed to create the effect. Once the width of the div is no longer large enough to contain all of the content, the max-width:0 property enables the width to become less than the width of the text content, but forces the text that can no longer fit to become overflow of the div itself. Thus, since the div now has text overflow and text-overflow: ellipsis is set, the text overflow is ellipsed (if that's a word).

This is very useful to us because otherwise we couldn't make this effect without a lot of messy JavaScript. Use case demo

_{Note: This answer describes the behavior and gives some insight as to why this is the case. It doesn't cover how display:table-cell overrides part of the max-width's effect.}

What does max-width: 0px do?

table {
  table-layout: fixed;
}

This fixes the cell widths to the value they are given. So if you do width: 30% on the cells, they won't resize based on their content and will maintain their set widths.

If only some of the cells are given a width value, the remaining cells will share the space available. Use this functionality as a replacement to max-width.

Using max-width: 0px is more of a quirk than reliable behaviour.

DEMO

max-width changes its value automatically

with max-width, you tell the browser what is max-width of the element.
if the max-width of the element is bigger than 500px it will make the height of the element bigger.

with max-width, you set the maximum width and therefore it can be smaller but not bigger than 500px

Why does max-width and width display a completely different result?

The difference between width: 100% and max-width:100% is that: First,
width define the width of the specific element while max-width define the
maximum size the element is allow to have link

What's the purpose of @media (max-width:-1)

@media (max-width:-1) {
    ...standard css stuff here
}

I believe this is invalid condition so it will never get executed

max-width of 100px vs width of 100px , why max-width is shorter than width?

You can think of the width property as being more strict than the max-width property.

• Width says: "You should be this width and nothing else."
• Max-width says: "Be whatever width you want, just not bigger than this width."

You can see this with the demo you provided. The natural width of the boxes is around 50px, not bigger than 100px so max-width doesn't really care. However, width sees that the boxes aren't 100px and so sets them to be 100px.

Media Query min-width: 320px and max-width

I think you can map media queries one by one according to the length and style you want to use, so you don't get confused

Hiding element with max-width:0?

this flex property is messing with what you're attempting to do here

&__list-item {
text-align: center;
display: flex;
/* flex: 1; */   

//if you comment out the line above it should work 
fine i guess

justify-content: center;
align-items: center;

}
