Quick overview:
Size content to viewport
The page content is too wide for the viewport, forcing the user to scroll horizontally. Size the page content to the viewport to provide a better user experience.
The page content is 322 CSS pixels wide, but the viewport is only 320 CSS pixels wide. The following elements fall outside the viewport:

Optimize CSS Delivery of the following:
Leverage browser caching
Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.
Leverage browser caching for the following cacheable resources: (expiration not specified)
Enable compression
Compressing resources with gzip or deflate can reduce the number of bytes sent over the network.
Enable compression for the following resources to reduce their transfer size by 8KiB (64% reduction).
Compressing could save 4.7KiB (60% reduction).
Optimize images
Properly formatting and compressing images can save many bytes of data.
Optimize the following images to reduce their size by 3.8KiB (5% reduction).
Losslessly compressing could save 1.2KiB (39% reduction).
Minify JavaScript
Compacting JavaScript code can save many bytes of data and speed up downloading, parsing, and execution time.
Minify JavaScript for the following resources to reduce their size by 2.7KiB (2% reduction).
Minifying could save 975B (15% reduction) after compression.
Minify CSS
Compacting CSS code can save many bytes of data and speed up download and parse times.
Minify CSS for the following resources to reduce their size by 963B (21% reduction).
Minifying could save 963B (21% reduction).
