Logical Properties
Learn when and how to use logical properties.
Logical properties in CSS allow you to create layouts that adapt to different writing modes and text directions. This can be particularly useful for creating more flexible and adaptable designs.
What is a Logical Property?
Logical properties are CSS properties that adapt to the writing mode and text direction of the document. Instead of using physical properties like margin-left or padding-right, you use logical properties like margin-inline-start or padding-inline-end.
<div class="flex ps-11 pe-11">
<div class="flex-1">First</div>
<div class="flex-1">Second</div>
</div>
In this example:
ps-11is the logical equivalent ofpadding-leftin left-to-right (LTR) writing mode andpadding-rightin right-to-left (RTL) writing mode.pe-11is the logical equivalent ofpadding-rightin LTR writing mode andpadding-leftin RTL writing mode.
Difference with Physical Properties
Physical properties are fixed and do not adapt to the writing mode or text direction. For example, margin-left always applies a margin to the left side of an element, regardless of the writing mode.
Logical properties, on the other hand, adapt to the writing mode and text direction. This makes them more flexible and suitable for creating layouts that need to support multiple languages and writing modes.
<!-- Physical Properties -->
<div class="mx-11"></div>
<div class="px-11"></div>
<!-- Logical Properties -->
<div class="ps-11 pe-11"></div>
<div class="ms-11 me-11"></div>
Why Use Logical Properties?
Logical properties provide several benefits:
- Flexibility: They adapt to different writing modes and text directions, making your layouts more flexible.
- Internationalization: They make it easier to create layouts that support multiple languages and writing modes.
- Consistency: They provide a consistent way to apply styles, regardless of the writing mode or text direction.
When to Use Logical Properties
Use logical properties when you need to create layouts that support multiple languages and writing modes. They are particularly useful for:
- Internationalization: Creating layouts that need to support both LTR and RTL languages.
- Responsive Design: Adapting layouts to different writing modes and text directions.
- Consistency: Ensuring consistent styling across different writing modes and text directions.
