Problem/Motivation

I found the issue using a 3 column layout. The width breakdown is 33/34/33. So, the middle columns is actually 1% wider than the other two. It seems not to be too much, but if you try to use images, it results in the middle one appearing missaligned.

Steps to reproduce

1. Select a theme other than olivero. For example: stark
2. Set the images width to 100%
In the file "core/modules/layout_builder/layouts/threecol_section/threecol_section.css" set:

.layout--threecol-section img {
  width: 100%;
  height: auto;
}

3. Using Layout builder create a three column section.
4. Create a custom block type with a field image
4. Create and add a block with the same image to each column. Since the images are set to have 100% width, ie. fill the width of the column, the middle one will appears to have a height greater than the others.

Proposed resolution

Use calc(100% / 3) to set the flex property so that they become 33.3333333333% (like bootstrap does)

Also, use

  .layout--threecol-section--33-34-33 > .layout__region {
    flex: 0 1 calc(100% / 3);
  }

instead of

  .layout--threecol-section--33-34-33 > .layout__region--first,
  .layout--threecol-section--33-34-33 > .layout__region--third {
    flex: 0 1 33%;
  }
  .layout--threecol-section--33-34-33 > .layout__region--second {
    flex: 0 1 34%;
  }
