W3 Schools is a site that promotes the learning of .net and application based programming languages. Here you can complete free self learning or pay to learn as part of a curriculum
When running the home page through a validation test at validator.w3.org the site returns with 6 errors and 3 warnings. This would suggest that the home page of w3schools.com does not meet the W3C markup standards for HTML code.
When navigating to another part of the site, specifically w3schools.com/spaces, and running it through the W3C markup validation results in 12 errors.
In total, between the two web pages, there are 18 errors and 3 warnings.
Here I will give a score from 1 out of 10, with 1 being the worst and 10 the best, on the below topics
When talking about design of a website we would normally go over visual design and structural design.
In regards to visual design, the website has a theme that it sticks to throughout the mulitple pages I've gone through. The layout of the navigation is quite lengthy but still a solid way of cutting down on the amount of pages a site uses.
I give this site a 7 out of 10 for it's visual design.
Now in regards to the code structure, there are too many glaring issues to ignore. Out of two pages there were a total of 18 errors showing that there are some major issues with this HTML code. However, I've clicked through the site and found no broken links or major visual bugs.
I give this site a 5 out of 10 for it's structural design.
As I stated earlier I did click through the site some more than required and noticed no broken links and no visual issues. I was able to used the HTML editor the site linked to and was able to access the syntax reference directory for 8 programming languages.
I give this site an 8 out of 10 for it's site usability
As a training tool W3 Schools does do a great job at getting people new to programming a foot in the door. While the site may have some syntax issues, a normal users sees very little of this since there are little to no visual issues or broken links.
I objectively believe that this site does meet its purpose.
