--description--
Puedes agregar otro nivel de organización en tu documento HTML dentro de las etiquetas html
con los elementos head
y body
. Cualquier código con información sobre tu página iría dentro de la etiqueta head
. Entonces, cualquier código con el contenido de la página (lo que se muestra para un usuario) iría dentro de la etiqueta body
.
Elementos de metadatos, tales como link
, meta
, title
, y style
, típicamente van dentro del elemento head
.
Aquí hay un ejemplo de la disposición de una página:
<!DOCTYPE html>
<html>
<head>
<meta />
</head>
<body>
<div>
</div>
</body>
</html>
--instructions--
Edita el código para que haya un head
y un body
. El elemento head
solo debe incluir title
, y el elemento body
solo debe incluir h1
y p
.
--hints--
Solo debe haber un elemento head
en la página.
const headElems = code.replace(/\n/g, '').match(/\<head\s*>.*?\<\/head\s*>/g);
assert(headElems && headElems.length === 1);
Solo debe haber un elemento body
en la página.
const bodyElems = code.replace(/\n/g, '').match(/<body\s*>.*?<\/body\s*>/g);
assert(bodyElems && bodyElems.length === 1);
El elemento head
debe ser hijo del 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);
El elemento body
debe ser hijo del 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);
El elemento head
debe envolver alrededor un 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);
El elemento body
debe envolver ambos elementos h1
y 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);
