Placeholder Mixin in SCSS/CSS
Question:
How to create a mixin for placeholders in SASS that allows the passing of static CSS without syntax errors?
Answer:
To achieve seamless passing of static CSS in a placeholder mixin, we can utilize the @content directive.
Updated Mixin:
<code class="scss">@mixin placeholder { ::-webkit-input-placeholder {@content} :-moz-placeholder {@content} ::-moz-placeholder {@content} :-ms-input-placeholder {@content} }</code>
Usage:
<code class="scss">@include placeholder { font-style:italic; color: white; font-weight:100; }</code>
Advanced Mixin (Sass 3.4 and above):
For enhanced flexibility, you can use the following mixin to support both nested and unnested usage:
<code class="scss">@mixin placeholder { @include optional-at-root('::-webkit-input-placeholder') { @content; } @include optional-at-root(':-moz-placeholder') { @content; } @include optional-at-root('::-moz-placeholder') { @content; } @include optional-at-root(':-ms-input-placeholder') { @content; } }</code>
This mixin provides a more robust placeholder approach that works across various CSS selectors and nested elements.
