Programming Assign. Unit 1 1. Identify 3 websites, which you've visited in the past. Run the HTML validating software against each site. You can select any of the validating tools available online. Here are the websites I visited: 1. CNN: https://edition.cnn.com/ 2. Fox News: https://www.foxnews.com/ 3. NBC News: https://www.nbcnews.com/ I checked all of those using the "w3c markup validation service". 2. Provide comments on the results of your exercise for each website. Make sure to list any problems identified. Also, provide a link to the validation tool you used. 1.cnn.com Validator link: https://validator.w3.org/nu/?doc=https%3A%2F%2Fedition.cnn.com %2F Here are some of the errors and warnings that the validator identified: • The html tag was missing the 'lang' attribute. • A meta element with an http-equiv attribute whose value is X-UA-Compatible  must have a content attribute with the value lE=edge.  Bad value text/html for attribute content on element meta • A document must not include both a meta element with an http-equiv attribute  whose value is content-type, and a meta element with a charset attribute. • Bad value for attribute href on element link: Must be non-empty. • CSS: cursor: hand is not a cursor value. • CSS: transition: scale(1.3,1.3) is not a transition value. • width: col(7) is not a width value. • The type attribute on the li element is obsolete. Use CSS instead. • Attribute mode is not allowed on element li at this point. 2.foxnews.com Validator link: https://validator.w3.org/nu/?doc=https%3A%2F%2Fwww.foxnews.com %2F The validator included a total of 153 errors and warnings. Many of those were repetitive and happened multiple times on the page.
