CSS - Targeting elements that are the immediate siblings following a line break

Imagine a scenario where there is a div wrapper containing multiple elements set as inline. As the width of the div decreases, the elements automatically move to new lines. Everything seems fine so far.

Now the challenge is to add a CSS :before content to the child elements, except the ones that are at the beginning of each line...

Is it possible to use only CSS to determine if an element is the first one after a line break?

UPDATE

Consider this example... http://jsfiddle.net/kagfqt9j/

When the div's width is such that the children break into three lines, a "|" divider is applied using :before. However, we want to avoid having the :before attached to the beginning of each line.

Therefore, is there a way to detect the first element after a line break?

Note: Switching to :after won't work because it would just shift the issue to the end of the lines. That's not a viable solution either.

Answer №1

In the event that your situation involves a fiddle, consider using a container with overflow:hidden and text-align left. You can then utilize this method to position the pseudo outside of the container with a negative margin: http://jsfiddle.net/abc123xyz/

a {
    display: inline-block;
    margin-right:0.25em;
    text-decoration:none; /* for demonstration purposes */
}

a:before {
    content: "| "; /* adds extra white-space next to the pipe */
    margin-left:-0.25em;
    color:black; /* for demonstration purposes */
    pointer-events:none; /* for demonstration purposes */
}

JavaScript solution

let previousOffsetTop = -1;
let items = document.querySelector('.items');

for (let i = 0; i < items.length; i++)
{
  if (items[i].offsetTop !== previousOffsetTop)
    Sys.UI.DomElement.addCssClass(items[i], 'firstItem');
  else
    Sys.UI.DomElement.removeCssClass(items[i], 'firstItem');

  previousOffsetTop = items.offsetTop;

}

Answer №3

Unfortunately, achieving this using CSS alone is not feasible.

An alternative solution could involve utilizing Javascript or jQuery to locate the position of each element and identify which one is situated farthest to the left within the parent container.
