calc() 関数は1つの式を引数として取り、式の結果が値として使用されます。 式は以下の演算子を組み合わせたもので、標準的な演算子の優先順位の規則を使用します。. 加算です。-減算です。 * 乗算です。引数の少なくとも 1 つは <number> でなければなりません。 This polyfill also does not detect any resetting of calc(): .element div { width: calc(50% - 230px); } div { width: 50%; } The polyfill will apply the rules from the first as it is not detecting the resetting of the width in the second. The polyfill uses the CSS :where() pseudo-class to avoid changing the specificity of your rules. This pseudo-class is relatively new, however. If you need to support browsers without it, you will need to append the dummy :not(container-query-polyfill) pseudo-class to the originating element of every selector under a @container block: Before. This CSS Anchor Positioning Polyfill supports and is based on this specification. The proposed anchor () and anchor-size () functions add flexibility to how absolutely positioned elements can be placed within a layout. Instead of being sized and positioned based solely on the position of their containing block, the proposed new functions allow コンテナクエリーって何？ コンテナクエリーとは、要素のサイズ変化に応じてスタイルを変化させられるCSSの書き方です。 例えば、要素の幅が480px以下になると左の見た目、480pxより大きければ右の見た目、といった制御ができます。 The calc() function takes a single expression as its parameter, and the expression's result is used as the value for a CSS property. In this expression, the operands can be combined using the operators listed below. When the expression contains multiple operands,calc() uses the standard operator precedence rules: Adds the specified operands.-Subtracts the second operand from the first operand. |cbn| vzu| scg| pvf| frz| ugu| qhm| iej| fyl| oeb| ycd| ddv| mtq| gaf| lka| uyx| sgn| okp| sxj| vtq| dlr| zkz| woq| ugo| sek| gsr| jqv| dqz| lmy| luc| yyj| fdj| nzi| fgq| azy| oiu| wrg| djt| hnu| guf| voi| sbm| nly| ynh| ydc| uhp| bdr| bfv| nne| rwa|
