    Hello @webqueenhtc !

    Hope you’re doing well today!

    The CSS mentioned in the results is not actually CSS code being added by Hummingbird itself – it’s the CSS which was already present on the site and was processed by Hummingbird to perform the optimisations. You can confirm that by:

    – opening the mentioned files and checking the handles mentioned at the top of each file – those will tell you which original files from your site are included in the processed file
    – deactivating Asset Optimisation and checking with GTMetrix to see the difference and the original files

    We have a guide here which you can use to further improve your site’s performance by adjusting the settings in the Asset Optimisation section:

    I click on your link above, but I don’t have the option – “see page unminified” from my free version.

    I click on Hummingbird from my dashboard, in the “Asset Optimization”, it is as follow:

    Assets: – Speedy (recommended) was chosen by default
    Configurations ->Files: CSS files, JavaScript files & Fonts was checked

    So I should unchecked them?

    Hi @webqueenhtc

    Settings that you currently have are “safe settings” meaning that they do help to some degree (in most cases it’s sufficient) while the risk of anything “breaking” on the site is nearly none.

    However, if this kind of optimization is not enough, what you’d need to do would be:

    1. go to the “Hummingbird -> Asset Optimization” page and switch from “Automatic” to “Manual”; when asked if to keep current configuration – confirm;

    2. it will then give you a list of CSS and JS files and next to each of them there’ll be a set of buttons that let you enable certain optimization options for each file separately.

    Please refer to the docs that my colleague shared previously for more details on this but in general – the goal here would be to have

    – as many CSS files set to be combined, inlined and moved to footer as possible without breaking the site
    – and as many JS files set to be combined, moved to footer and loaded after page is loaded as possible without breaking the site

    This is a bit of “experimental” work and might take some effort and “playing around” but since it gives very granular control over entire optimization process, it usually gives really significant results.

    Note: it may not be possible to fully eliminate all “render blocking resources” as it also depends on how the site is configured, what plugins and theme it’s using and how they work and how their scripts “interact”. But it would let you limit the number of those “render blocking resources” to absolute minimum.

    Kind regards,

    Hello @webqueenhtc ,

    We haven’t heard from you for some time now, so it looks like you don’t need our assistance anymore.

    Feel free to re-open this ticket if needed.

    Kind regards
