# Internationalization In CSS
When we work with **multilingual sites,** we have to adjust our elements as per **writing mode, directionality, and text orientation.**
### text-align —
In many languages, texts work from **LTR(Left to Right)** like in English, but in many languages, texts also work from **RTL(Right to Left)** like French**.** So if your application works in both languages, then you have to adjust your text alignment as per the language in which your application is running on the browser.
suppose we have added **text-align: right;** then for English Lang it will wotk correctly. but for French we have to apply **text-align: left;** for same Element. because English works as **LTR** and French works as **RTL.**
So using only 1 property which can work **text-align: right;** for LTR and **text-align: left;** for RTL. that will overcome line of code and customization as per lang.
So for maintaining this, css provides some text-alignment properties which should be used for multilingual sites.
```
## Don’t
.alignRight{
text-align: right;
}
.alignLeft{
text-align: left;
}
## Do
.alignRight{
text-align: end;
}
.alignLeft{
text-align: start;
}
```
## Margin(based on **writing mode)**—
These properties correspond to the **margin-top, margin-bottom, margin-left, and margin-right** properties. The mapping depends on the element’s writing mode, direction, and text orientation.
**Problem**\- when we change writing mode from **vertical-lr** to **vertical-rl or** vice versa, then these properties should work other way round. Ex **margin-top** should work as **margin-bottom** on change of writing mode. But for getting this behaviour we have to write CSS 2 times based on writing mode. But CSS also provides properties by which we have to write CSS only 1 time and on change of writing mode we don’t need any adjustment. it will automaticaly start behaving other way round.
```
#### Don’t
.`margin-top`{
`margin-top`: 10px;
}
.`margin-bottom`{
` margin-bottom`: 10px;
}
.`margin-left`{
`margin-left`: 10px;
}
.`margin-right`{
`margin-right`: 10px;
}
#### Do
.`margin-top`{
`margin-block-start`: 10px;
}
.`margin-bottom`{
`margin-block-end`: 10px;
}
.`margin-left`{
`margin-inline-start`: 10px;
}
.`margin-right`{
`margin-inline-end`: 10px;
}
```
`**vertical-lr**` a mapping equal to
```
margin-block-start = margin-left
margin-block-end = margin-right
margin-inline-start = margin-top
margin-inline-end = margin-bottom
```
`**vertical-rl**` a mapping equal to
```
margin-block-start = margin-right
margin-block-end = margin-left
margin-inline-start = margin-top
margin-inline-end = margin-bottom
```
### HTML lang attribute-
it is used to identify the language of text content on the web. This information helps search engines return language-specific results, and it is also used by screen readers that switch language profiles to provide the correct accent and pronunciation
```
#### Don’t
#### Do
Even more specific
```
### Identify a linked document’s language
**use "hreflang" attribute if linked page is in other langs**
```
German version
```
**if the link text is also in other "lang" then define lang attribute too**
```
Deutsche Version
```
### Happy learning …👏👏👏
