In "Projects of the week" block, link "See more news &" is not complete and throws a warning "character & is the first character of a delimiter but occurred as data". The source literally has the following text: "See more news & reviews", but & should be replaced with &

In "Learn" block, star rating ul/li tags have invalid id's as they duplicate for each of the items in the block and validation fails with an error.

For example:

<li style="width: 100%;" class="ezsr-current-rating" id="ezsr-current-rating">Currently <span>5</span> out of 5 Stars.</li>

Should be changed to:

<li style="width: 100%;" class="ezsr-current-rating" id="ezsr-current-rating-xyz">Currently <span>5</span> out of 5 Stars.</li>

where xyz is the node/object id of the item.

Subsequently, all other li tags that relate to the specific id should be changed as well.
