Optimizations

Website

FontAwesome

Well... we only need a couple of icons, so loading in a selected set of icons would be better instead of the whole library. To be continued...

Minify javascript files

Don't forget to minify (or re-minify after changes) the javascript files.

Lazy load images and background images

Background image:

<div class="b-lazy" data-src=""></div>

Image:

<img class="b-lazy" src="data:image/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==" data-src="">

You can also add data-src-small="" but it's optional

Loading external css or javascript

• Always try to use https:// or //assets.site.tld (the last one uses the http(s) protocol of the website)

• For css, load it in the deferred stylesheets part of Head.html.twig: <noscript id="deferred-styles"> ... </noscript>

• For javascript, load it defferred: <script defer src=""></script>

Server

SSL, https/2 and GZIP

When activating SSL, try enabling https/2 for speed gain (the assets of this Fork theme or optimized for https/2)

You can enable this in my.combell.be of the hosting package under "Site instellingen > http/2"

Also enable GZIP compression in the general tab of "Site instellingen > algemeen"

ImageOptim images

ImageOptim the theme images and /src/Frontend/Files folder from the server (the live files)

Cookie-less domain

Add this to the .htaccess: (always test this!)
This removes the cookies from al the loaded assets for page speed gains.

# file caching in browser
<IfModule mod_expires.c>
    ExpiresActive On
    <FilesMatch "\.(?i:ico|gif|jpe?g|png|svg|svgz|js|css|swf|ttf|otf|woff|eot)$">
        ExpiresDefault "access plus 12 montsa"
		RequestHeader unset Cookie
		Header unset Cookie
		Header unset Set-Cookie
    </FilesMatch>
</IfModule>
