Raio da borda

Adicione classes a um elemento para arredondar facilmente seus cantos.

Example rounded image 75x75 Example top rounded image 75x75 Example right rounded image 75x75 Example bottom rounded image 75x75 Example left rounded image 75x75 Completely round image 75x75 Rounded pill image 150x75
<img src="..." class="rounded" alt="...">
<img src="..." class="rounded-top" alt="...">
<img src="..." class="rounded-end" alt="...">

<img src="..." class="rounded-start" alt="...">
<img src="..." class="rounded-circle" alt="...">
<img src="..." class="rounded-pill" alt="...">

Tamanhos

Use as classes de dimensionamento para cantos arredondados maiores ou menores. Os tamanhos variam de 0a 3e podem ser configurados modificando a API de utilitários.

Example non-rounded image 75x75 Example small rounded image 75x75 Example default rounded image 75x75 Example large rounded image 75x75
<img src="..." class="rounded-0" alt="...">
