a
O elemento <a> do SVG cria um hiperlink para outras páginas da web, arquivos, locais na mesma página, endereços de email ou qualquer outra URL. É muito semelhante ao elemento <a>
do HTML.
O elemento <a>
do SVG é um contêiner, o que significa que você pode criar um link em torno do texto (como em HTML), mas também em torno de qualquer elemento.
<svg viewBox="0 0 100 100" xmlns="https://www.w3.org/2000/svg">
<!-- A link around a shape -->
<a href="/docs/Web/SVG/Element/circle">
<circle cx="50" cy="40" r="35" />
</a>
<!-- A link around a text -->
<a href="/docs/Web/SVG/Element/text">
<text x="50" y="90" text-anchor="middle"><circle></text>
</a>
</svg>
/* As SVG does not provide a default visual style for links,
it's considered best practice to add some */
@namespace svg url(https://www.w3.org/2000/svg);
/* Necessary to select only SVG <a> elements, and not also HTML’s.
See warning below */
svg|a:link,
svg|a:visited {
cursor: pointer;
}
svg|a text,
text svg|a {
fill: blue; /* Even for text, SVG uses fill over color */
text-decoration: underline;
}
svg|a:hover,
svg|a:active {
outline: dotted 1px blue;
}
Aviso: Como esse elemento compartilha seu nome de tag com o elemento <a>
do HTML, selecionar a
com CSS ou querySelector
, pode ser aplicar ao tipo errado de elemento. Experimente usar a regra @namespace para distinguir os dois.
