I'm gradually digging into the web world, and today I noticed something unusual in my code, good, unusual more or less let's go to the examples.
In this code I use type="text / css"
<link rel="stylesheet" type="text/css" href="caminho aqui">
And in this I no longer use
<link rel="stylesheet" href="caminho aqui">
Both work, but is there a problem if I do not set the type? I need a very concrete answer that heals my doubt.
Nowadays it is no longer necessary to use the type attribute.
In version 4 of HTML was still referred to the attribute, but indicating that it "gives a suggestion" to the browser about the content, and by the text it is understood that it was not mandatory:
This attribute gives an advisory hint as to the content type of the content available at the link target address. [...] Authors who use this attribute ...
In HTML 5 specification is still clearer: / p>
The type attribute gives the MIME type of the linked resource. It is purely advisory.
The attribute is purely a suggestion (translating freely).
