If I have external stylesheets being included in the <head></head> section of my HTML page, will they be loaded before the HTML and immediately applied upon rendering? Let me present my specific use case.
External styles.css file:
form label {
display: none;
}
Page containing form:
<head>
<link rel="stylesheet" href="styles.css" type="text/css" />
</head>
<form action="process.php" method="post">
<label for="name">Name</label>
<input type="text" id="name" name="name" />
</form>
Can I be confident that the labels will be invisible upon page load (no flickering due to CSS downloading)?
Otherwise, I can add the style attribute inline, but that can be a maintenance nightmare.

External CSS Each HTML page must include a reference to the external style sheet file inside the <link> element, inside the head section.
External stylesheets use the <link> tag inside the head element. The rel attribute explains the relation the link has to our document. The value in this case will always be stylesheet , since that is what we're creating a link to. The href attribute is the link to our stylesheet.
Apply styles to a whole website by placing the CSS into an external stylesheet. An external style sheet is a separate file where you can declare all the styles that you want to use on your website. You then link to the external style sheet from all your HTML pages.
CSS can be added to HTML documents in 3 ways: Inline - by using the style attribute inside HTML elements. Internal - by using a <style> element in the <head> section. External - by using a <link> element to link to an external CSS file.
If you include the CSS in the head section, you can be confident that the label will not show.
The HTML is downloaded first. The browser starts reading the html from the top, and starts fetching all CSS and JavaScript files referenced in the HEAD section. The page will not be painted (shown) until all the CSS and JavaScript files in the HEAD have been downloaded and evaluated.

Style sheets don't prevent the document from being downloaded, but the browser won't render the document until all of the linked stylesheets have been downloaded and loaded into the DOM.
This is so that the browser doesn't need to render the page twice (wasting time in the process), and so that an unstyled page won't flash in front of the user before the stylesheets have been downloaded and parsed.
