HTML&CSSコース

sass/scs->sassには2つのsass構文があり、scss構文(両方ともsass!これはどの構文を使用するかによって異なります)
Dart Sassは最近流行っています
node-sassの代わりにDart Sassを使用
sass:math
math:div(12px, 2);package.json

{
  "scripts": {
    "start": "npm run watch",
    "sass": "sass sass:css",
    "watch": "npm run sass -- --watch"
  },
  "devDependencies": {
    "sass": "^1.38.0"
  }
}

scriptはコマンドを設定する部分です(startを実行するとrunは書かずnpm startだけで実行できますが、その他はrunキーが必要です!)devDependenciesには、npmを使用してインストールされたパッケージがリストされています.
watch部分の--は区別のため、前に1つ追加します.

開発にはstyle.css.mapファイルが必要です!(ソースマッピング)

 npm i -D rimraf
 

rimarfパッケージのインストール

@use './base';
@use './color';

dart scss-->@importの代わりに@useを使用!_functions.scss

// 루트 요소 기본 단위 --------------------------------------------------------------- /
$root-value: 16px !default;

// 단위 제거 함수 ------------------------------------------------------------------ /
@function removeUnit($value){
  @return ($value / ($value * 0 + 1));
}

// px을 rem 단위로 변경하는 함수 ------------------------------------------------------- /
@function rem($value, $base: $root-value){
  @return (removeUnit($value / $base)) * 1rem;
}

// px을 em 단위로 변경하는 함수 ------------------------------------------------------- /
@function em($value, $base: $root-value){
  @return (removeUnit($value / $base)) * 1em;
}

Input要素のクロスブラウズに使用するcss

.form-input::-ms-clear, .form-input::-webkit-search-cancel-button, .form-input::-webkit-search-results-button {
  display: none;
}
.form-input::-ms-reveal {
  display: none;
}
.form-input::placeholder, .form-input::-ms-input-placeholder {
  color: #BDBDBD;
}

apperance: none; --> 요소내장구성요소제거

.form-group [class$="__label"]

input.scss

@use './base' as *;

    &:focus {

.form-input {
    //  중첩 패턴을 쓰면서도 명시도 점수를 낮출 수 있음
    &__label {
        display: block;
        color: $form-text-color;

今日はSassをインストールして、Sass文法で前のSecretCode課題を書き直して熟知する時間です.
