テキストの位置調整
テキストの位置調整クラスを使用して、テキストを簡単に配置できます。 開始、終了、中央揃えには、グリッドシステムと同じビューポート幅のブレイクポイントを使用するレスポンシブクラスが利用できます。
Start aligned text on all viewport sizes.
Center aligned text on all viewport sizes.
End aligned text on all viewport sizes.
Start aligned text on viewports sized SM (small) or wider.
Start aligned text on viewports sized MD (medium) or wider.
Start aligned text on viewports sized LG (large) or wider.
Start aligned text on viewports sized XL (extra-large) or wider.
<p class="text-start">Start aligned text on all viewport sizes.</p>
<p class="text-center">Center aligned text on all viewport sizes.</p>
<p class="text-end">End aligned text on all viewport sizes.</p>
<p class="text-sm-start">Start aligned text on viewports sized SM (small) or wider.</p>
<p class="text-md-start">Start aligned text on viewports sized MD (medium) or wider.</p>
<p class="text-lg-start">Start aligned text on viewports sized LG (large) or wider.</p>
<p class="text-xl-start">Start aligned text on viewports sized XL (extra-large) or wider.</p>
テキストの折り返しとオーバーフロー
.text-wrap
でテキストを折り返しできます。
<div class="badge bg-primary text-wrap" style="width: 6rem;">
This text should wrap.
</div>
.text-nowrap
にするとテキスト折り返しを抑止します。
<div class="text-nowrap bg-body-secondary border" style="width: 8rem;">
This text should overflow the parent.
</div>
単語の区切り
.text-break
を使って word-wrap: break-word
とword-break: break-word
を設定することで、長い文字列がレイアウトを崩すのを防ぎます。ブラウザのサポート範囲を広げるためoverflow-wrap
の代わりにより一般的なword-wrap
を使用し、フレックスコンテナの問題を避けるために非推奨のword-break: break-word
を追加します。
mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm
<p class="text-break">mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm</p>
.text-break
が削除されています。
テキストの変換
テキストの大文字・小文字化、キャピタライズクラスを利用できます。
Lowercased text.
Uppercased text.
CapiTaliZed text.
<p class="text-lowercase">Lowercased text.</p>
<p class="text-uppercase">Uppercased text.</p>
<p class="text-capitalize">CapiTaliZed text.</p>
.text-capitalize
が各単語の最初の文字を変更するだけで、他の文字の大文字小文字は影響されないことに注意してください。
フォントサイズ
font-size
を素早く変更することができます. 見出しクラス(例:.h1
~.h6
)はfont-size
, font-weight
, line-height
を適用しますが、これらのユーティリティはfont-size
のみ 適用します。これらのユーティリティのサイズは、HTMLの見出し要素と一致しているので、数が増えるにつれて、そのサイズは小さくなります。
.fs-1 text
.fs-2 text
.fs-3 text
.fs-4 text
.fs-5 text
.fs-6 text
<p class="fs-1">.fs-1 text</p>
<p class="fs-2">.fs-2 text</p>
<p class="fs-3">.fs-3 text</p>
<p class="fs-4">.fs-4 text</p>
<p class="fs-5">.fs-5 text</p>
<p class="fs-6">.fs-6 text</p>
Sassマップの$font-sizes
を変更することで、利用可能なfont-size
をカスタマイズすることができます。
フォントの太さと斜体
テキストのfont-weight
やfont-style
を変更できます。 font-style

等幅フォント
.font-monospace
を使って等幅フォントに変更できます。
