After extensive research, I discovered that any elements utilizing a retina display or similar technology require unique styling for margins, padding, width, height, font-size, and more compared to standard displays.
Given the characteristics of retina displays, the solution was relatively straightforward (albeit tedious). Leveraging Sass (and bootstrap), I devised a series of mixins like the following:
@import "../../global/variables";
@import "structure";
@mixin make-font($size) {
font-size: 1 * $size;
@include iphone-portrait {
font-size: 2 * $size;
}
}
@mixin header-font {
@include make-font($h1);
}
@mixin lead-font {
@include make-font($lead);
}
@mixin default-font {
@include make-font($p);
}
@mixin small-font {
@include make-font($small);
}
@mixin font-size($size) {
@include make-font($size);
}
The differentiation in handling fonts for iPhone screens can be observed in the code above. The mixin for iphone-portrait was sourced from , with modifications made to suit my needs.
@mixin iphone-portrait {
@media only screen and (min-device-width : 414px) and (max-device-width : 736px) and (orientation : portrait) {
@content;
}
@media only screen and (min-device-width : 320px) and (max-device-width : 568px) and (orientation : portrait) {
@content;
}
@media only screen and (min-device-width : 320px) and (max-device-width : 480px) and (orientation : portrait) {
@content;
}
}
Additional media queries can be appended to simplify the process further. This methodology primarily focuses on fonts, though similar mixins were crafted for other design elements. For instance, consider the customization done for the navbar:
.navbar-default {
@include make-navbar;
@include lead-font;
position: fixed;
top: 0;
width: 100%;
background-color: $white-sky;
color: $midnight-blue;
margin: 0;
border: 0;
z-index: 1;
box-shadow: none;
border-radius: 0;
@include iphone-portrait {
@include make-navbar(2);
}
}
The corresponding mixin for the navbar had a structure akin to this:
@mixin make-navbar($multiplyer: 1) {
// Styles here
}
// Additional mixin for sub-height calculations
The flexibility of using a $multiplyer variable facilitates easy scaling. By adjusting the value passed to the mixin, it's possible to double or modify element sizes as needed.
This method has been successfully tested and verified. It offers adaptability for various scenarios where different scaling factors may be required.
