--description--
Puoi aggiungere un altro livello di organizzazione nel tuo documento HTML all'interno dei tag html con gli elementi head e body. Qualsiasi markup con informazioni sulla tua pagina dovrebbe essere inserito nel tag head. Qualsiasi markup con il contenuto della pagina (quello che viene visualizzato dall'utente) dovrebbe invece andare nel tag body.
Gli elementi contenenti metadati, come link, meta, title, e style, normalmente vanno all'interno dell'elemento head.
Ecco un esempio del layout di una pagina:
<!DOCTYPE html>
<html>
<head>
<meta />
</head>
<body>
<div>
</div>
</body>
</html>
--instructions--
Modifica il markup in modo che ci siano una head e un body. L'elemento head dovrebbe includere solo il title, e l'elemento body dovrebbe includere solo h1 e p.
--hints--
Ci dovrebbe essere un solo elemento head nella pagina.
const headElems = code.replace(/\n/g, '').match(/\<head\s*>.*?\<\/head\s*>/g);
assert(headElems && headElems.length === 1);
Ci dovrebbe essere solo un elemento body nella pagina.
const bodyElems = code.replace(/\n/g, '').match(/<body\s*>.*?<\/body\s*>/g);
assert(bodyElems && bodyElems.length === 1);
L'elemento head dovrebbe essere un figlio dell'elemento html.
const htmlChildren = code
.replace(/\n/g, '')
.match(/<html\s*>(?<children>.*)<\/html\s*>/);
let foundHead;
if (htmlChildren) {
const { children } = htmlChildren.groups;
foundHead = children.match(/<head\s*>.*<\/head\s*>/);
}
assert(foundHead);
L'elemento body dovrebbe essere un figlio dell'elemento html.
const htmlChildren = code
.replace(/\n/g, '')
.match(/<html\s*>(?<children>.*?)<\/html\s*>/);
let foundBody;
if (htmlChildren) {
const { children } = htmlChildren.groups;
foundBody = children.match(/<body\s*>.*<\/body\s*>/);
}
assert(foundBody);
L'elemento head dovrebbe racchiudere l'elemento title.
const headChildren = code
.replace(/\n/g, '')
.match(/<head\s*>(?<children>.*?)<\/head\s*>/);
let foundTitle;
if (headChildren) {
const { children } = headChildren.groups;
foundTitle = children.match(/<title\s*>.*?<\/title\s*>/);
}
assert(foundTitle);
L'elemento body dovrebbe racchiudere entrambi gli elementi h1 e p.
const bodyChildren = code
.replace(/\n/g, '')
.match(/<body\s*>(?<children>.*?)<\/body\s*>/);
let foundElems;
if (bodyChildren) {
const { children } = bodyChildren.groups;
const h1s = children.match(/<h1\s*>.*<\/h1\s*>/g);
const ps = children.match(/<p\s*>.*<\/p\s*>/g);
const numH1s = h1s ? h1s.length : 0;
const numPs = ps ? ps.length : 0;
foundElems = numH1s === 1 && numPs === 1;
}
assert(foundElems);
