# Breakpoints
|
|
|
|
Breakpoints are used for responsive layout
|
|
|
|
## Screen Sizes
|
|
|
|
There are 4 screen sizes that make up the breakpoints for the MetaMask extension
|
|
|
|
- base: `0px`
|
|
- sm: `576px`
|
|
- md: `768px`
|
|
- lg: `1280px`
|
|
|
|
### SCSS
|
|
|
|
There are Sass variables and mixins available for use for both min and max screens sizes
|
|
|
|
### Variables
|
|
|
|
```css
|
|
$screen-sm-max /* 575px */
|
|
$screen-md-max /* 767px */
|
|
$screen-lg-max /* 1279px */
|
|
|
|
$screen-sm-min /* 576px */
|
|
$screen-md-min /* 768px */
|
|
$screen-lg-min /* 1280px */
|
|
```
|
|
|
|
### Mixins
|
|
|
|
```css
|
|
/* Max screen size */
|
|
@include screen-sm-max {
|
|
/* equivalent css @media screen and (max-width: 575px) */
|
|
}
|
|
@include screen-md-max {
|
|
/* equivalent css @media screen and (max-width: 767px) */
|
|
}
|
|
@include screen-lg-max {
|
|
/* equivalent css @media screen and (max-width: 1279px) */
|
|
}
|
|
|
|
/* Min screen size */
|
|
@include screen-sm-min {
|
|
/* equivalent css @media screen and (min-width: 576px) */
|
|
}
|
|
@include screen-md-min {
|
|
/* equivalent css @media screen and (min-width: 768px) */
|
|
}
|
|
@include screen-lg-min {
|
|
/* equivalent css @media screen and (min-width: 1280px) */
|
|
}
|
|
```
|
|
|
|
Migrating from the old sass variables to the new mixins looks like this
|
|
|
|
```css
|
|
/* Max width */
|
|
/* Instead of the media query and sass variable */
|
|
@media screen and (max-width: $break-small) {
|
|
right: 16px;
|
|
}
|
|
|
|
/* Use the sass mixin */
|
|
@include screen-sm-max {
|
|
right: 16px;
|
|
}
|
|
|
|
/* Min width */
|
|
/* Instead of the media query and sass variable */
|
|
@media screen and (min-width: $break-large) {
|
|
left: 16px;
|
|
}
|
|
|
|
/* Use the sass mixin */
|
|
@include screen-sm-min {
|
|
left: 16px;
|
|
}
|
|
```
|
|
|
|
## Takeaways
|
|
|
|
- Try to avoid using static media queries in your code.
|
|
- Try to use the provided SCSS mixins
|
|
|
|
### ❌ Don't do this
|
|
|
|
Don't use static media queries in your code.
|
|
|
|
```css
|
|
/**
|
|
* Don't do this
|
|
* Static media queries create inconsistency and could break the UI if we want to update them in future
|
|
**/
|
|
.account-menu {
|
|
@media screen and (min-width: 769px) {
|
|
right: calc((100vw - 80vw) / 2);
|
|
}
|
|
|
|
@media screen and (min-width: 1281px) {
|
|
right: calc((100vw - 65vw) / 2);
|
|
}
|
|
}
|
|
```
|
|
|
|
### ✅ Do this
|
|
|
|
Do use the provided Sass mixins
|
|
|
|
```css
|
|
.account-menu {
|
|
@include screen-md-min {
|
|
right: calc((100vw - 80vw) / 2);
