html - paragraph tag not closed? -

-

i simplified html code down this

<!doctype html> <body> <div class="index-div">     <p id="whoarewe">         <h2>who we?</h2>         wersfgse     </p> </div> </body> </html>

however, when run , open page source, says "no p element in scope p end tag seen". runs fine strange reason, intellij idea , firefox both show unnecessary /p tag. computer glitching out?

edit: chrome says it's ok see look

there's fixed set of elements, belonging phrasing content category, can children of <p> element:

phrasing content text of document, elements mark text @ intra-paragraph level. runs of phrasing content form paragraphs.

a abbr area (if descendant of map element) audio b bdi bdo br button  canvas cite code data datalist del dfn em embed iframe img input ins kbd keygen label map mark math meter noscript object output  progress q ruby s samp script select small span strong sub sup svg template textarea time u var video wbr text

<h2> element, many other block-level ones, doesn't belong here. in case, <p> element closes automatically. quoting the docs:

a p element's end tag may omitted if p element followed address, article, aside, blockquote, div, dl, fieldset, footer, form, h1, h2, h3, h4, h5, h6, header, hgroup, hr, main, nav, ol, p, pre, section, table, or ul, element, or if there no more content in parent element , parent element not element.

in particular case, structure of dom follows:

<p id="whoarewe"></p> <h2>who we?</h2> wersfgse </p>

... and, can see, end tag isn't welcome. actually, should grateful firefox dom inspector marking error. )

i'm trying apply flex button on firefox i'm having problem on chrome doesn't happens. this css: .button { display: inline-flex; align-items: center; } as can see in fiddle, "caret" word moved new line, happens if element <button> tag, <div> works expected. http://codepen.io/anon/pen/xblmgx is firefox bug or there css i'm missing? nevermind, looks "mr firefox" doesn't idea... <button> not implementable (by browsers) in pure css, bit of black box, perspective of css. means don't react in same way e.g. <div> would. this isn't specific flexbox -- e.g. don't render scrollbars if put "overflow:scroll" on button, , don't render table if put "display:table" on it. stepping further, isn't specific <button> . consider <fieldset> , <table> have special rendering behavior: data:text/html,<fieldset style="d...
