Answer 3

me-auto means "margin end auto". Which is actually:

margin-right: auto

me = margin-right and ms = margin-left

To verify my answer you can download the bootstrap 5.0 here: https://getbootstrap.com/docs/5.0/getting-started/download/

Open css/bootstrap.css file and then search for this className(me-auto) and you will find its css code there.

Answer 4

Quick answer

It's the preferable way to make spacings in Bootstrap 5, which is friendly for both LTR and RTL writing systems.

• me stands for margin-end.
• me-auto in LTR is equivalent to mr-auto in Bootstrap 4 and before.

Details if interested

Spacing classes in Bootstrap 5 are named using the format:

• {property}{sides}-{size} for xs,
• {property}{sides}-{breakpoint}-{size} for sm, md, lg, xl, and xxl.

Where property is one of:

• m - for classes that set margin
• p - for classes that set padding

Where sides is one of:

• t - for classes that set margin-top or padding-top
• b - for classes that set margin-bottom or padding-bottom
• s - (start) for classes that set margin-left or padding-left in LTR, margin-right or padding-right in RTL
• e - (end) for classes that set margin-right or padding-right in LTR, margin-left or padding-left in RTL
• x - for classes that set both *-left and *-right
• y - for classes that set both *-top and *-bottom
• blank - for classes that set a margin or padding on all 4 sides of the element

Where size is one of:

• 0 - for classes that eliminate the margin or padding by setting it to 0
• 1 - (by default) for classes that set the margin or padding to $spacer * .25
• 2 - (by default) for classes that set the margin or padding to $spacer * .5
• 3 - (by default) for classes that set the margin or padding to $spacer
• 4 - (by default) for classes that set the margin or padding to $spacer * 1.5
• 5 - (by default) for classes that set the margin or padding to $spacer * 3
• auto - for classes that set the margin to auto

Answer 5

For ul position left to right use

<ul class="nav justify-content-end">

me-auto meening bootstrap 5 margin end-auto

Answer 6

1. Without seeing code, we can't help about alignment left to right or you maybe use.

float:right or you can use this CSS:

.lefttoright {
  position: relative;
  right: 5px;
}

2. me-auto pushing two items to the right.

Answer 7

You can use mr-auto and ml-auto for right and left alignment respectively in Bootstrap 5.

class="navbar-nav mr-auto mb-2 mb-lg-0"

Answer 8

.me-auto {
  margin-right: auto !important;
}

The code above reveals the CSS rule using Firefox's Developer Tools inspection method.

Answer 9

ms / me are the Bootstrap 5 "non-directional" versions of ml / mr. By switching to ms / me the start / end is correct when the layout is oriented from right to left (RTL) https://getbootstrap.com/docs/5.2/utilities/spacing/#margin-and-padding

Bootstrap 4 => Bootstrap 5
ml = margin + left => ms = margin + start
mr = margin + right => me = margin + end
