Google Chrome Lighthouse Scan: Issues Detected

[nikolayg]

Environment

The demo pages linked from the main repo - e.g. https://mmistakes.github.io/so-simple-theme/

Expected behavior

I ran the Google Chrome Lighthouse scan on the sample page. There were a few reported issues with respect to accessibility, performance, and security. For example, the Previous button does not have enough contrast with the background and an old version of JQuery is used (which has vulnerabilities):

Steps to reproduce the behavior

Open the sample page https://mmistakes.github.io/so-simple-theme/ and run the Chrome Lighthouse tool.
