What is causing the border-right property to remain unchanged in RTL?

Question

What is causing the border-right property to remain unchanged in RTL?

Exploring the right-to-left direction in my HTML for languages like Arabic and Hebrew has been a challenge.

The issue I am encountering is that when switching to RTL, the border-right property does not adjust as expected. I initially assumed that the border-right would mirror the behavior of border-left in RTL mode.

What exactly does the RTL property do? Does it simply shift the content or are there additional implications? Before making changes such as swapping border-right to left in RTL scenarios, I want to fully understand the functionality of RTL. Any insights on this would be appreciated.

var rtl = document.getElementById('RTL');
var content = document.getElementById('content');
var currentState;
rtl.onclick = implementRTL;

function implementRTL() {
  currentState = content.getAttribute('dir');
  if (currentState == 'ltr') {
    content.setAttribute('dir', 'rtl');
  } else {
    content.setAttribute('dir', 'ltr');
  }
}

div {
  border: 10px solid #000;
  border-right: 10px solid red
}

<div id="content" dir="ltr">
  Hi Here is the content
</div>
<button id="RTL">
  RTL SWITCH
</button>

Answer №1

`border-inline-end`

This CSS property is used to define the right border in LTR text direction and the left border in RTL text direction. Additionally, there are also properties like border-inline-start for the opposite side border, and border-block-start and border-block-end for top and bottom borders respectively. These properties work seamlessly with vertical text as well.

var rtl = document.getElementById('RTL');
var content = document.getElementById('content');
var currentState;
rtl.onclick = implementRTL;

function implementRTL() {
  currentState = content.getAttribute('dir');
  if (currentState == 'ltr') {
    content.setAttribute('dir', 'rtl');
  } else {
    content.setAttribute('dir', 'ltr');
  }
}

div {
  border: 10px solid #000;
  /* border-right: 10px solid red; */ /* old */
  border-inline-end: 10px solid red; /* new */
}

<div id="content" dir="ltr">
  Hi Here is the content
</div>
<button id="RTL">

dir="ltr" determines the flow direction of content within a block-level element, affecting text, inline elements, and inline-block elements. It also establishes the default alignment of text and the direction in which cells flow in a table row.

To achieve this effect using CSS, you can utilize direction: rtl; like so:

.rtl {
  direction: rtl;
}
.element {
  border-right: 1px solid blue;
}
.rtl .element {
  border-right: none;
  border-left: 1px solid blue;
}

Alternatively, you could use:

.element {
  border-right: 1px solid blue;
}
#content:dir(rtl) .element { 
  border-right: none;
  border-left: 1px solid blue; 
}

Modifying the "dir" attribute in content to indicate either ltr or rtl will change the text direction. Adjusting the border-color of an element typically requires a hands-on approach. Below is a technique to achieve this:

HTML:

<div id="content" dir="rtl">
  Hello! This is the content
</div>
<button id="LR">
  LR SWITCH
</button>

CSS:

div,.divrtl {
  border: 10px solid #000;
  border-left: 10px solid blue;
}

.divltr {
  border: 10px solid #000;
  border-right: 10px solid blue;
}

JAVASCRIPT:

var d = document;
d.g = d.getElementById;

var lr = d.g('LR');
var con = d.g('content');
lr.addEventListener('click',function(){
  toggleDirection();
}); 

function setTextBorder(direction) {
  con.setAttribute('dir', direction);
  con.className = "div" + direction;
}

function getCurrentState() {
  return con.getAttribute('dir');
}

function toggleDirection() {
  (getCurrentState() == 'ltr')? setTextBorder('rtl') :setTextBorder('ltr');
}

const switchButton = document.querySelector('#ltr');
const targetElement = document.querySelector('#text-content');
function switchTextDirection(element) {
    const direction = element.attributes.direction.value;
    element.attributes.direction.value = direction === 'ltr' ? 'rtl' : 'ltr';
}
switchButton.addEventListener('click', function() {
    switchTextDirection(targetElement);
});

Answer 8

const switchButton = document.querySelector('#ltr');
const targetElement = document.querySelector('#text-content');
function switchTextDirection(element) {
    const direction = element.attributes.direction.value;
    element.attributes.direction.value = direction === 'ltr' ? 'rtl' : 'ltr';
