I have never used HTML or CSS before, and I'm curious about how they work in conjunction with Java. Do we use different languages in the same piece of code? Looking at the component pieces of an HTML file (the significance of each individual line) I would like to review the HTML in the HEAD at the top of the page I think I'm curious as to how websites like WAVE and W3C determine that a website is valid, as well as how Screen Readers and other accessibility tools would interpret a website that isn't valid. I am also curious to see if there are tools or such that accessibility tools would have to overcome the obstacles of invalid webs. Validation & accessibility I'm still finding a bit difficulty on understanding validators. What are some things that won't be validating? I think I'm confused if it is trying to validate the url or using the url to see if the website is validating and following the given guidelines.. W3C website was not able to resolve my confusion.. I want to talk more about accessibility and validators because it is something I've never heard of before! Validators? I *think* I understand the concept of a validator: it seems to be a tool used to assess how accessible HTML / CSS / websites generally are. But this could be wrong! But I feel like I don't really understand question 4. Technically, I don't think you *need* to use a validator, but I think you *should*. The other 3 answer options seemed less logical to me, so I went with "required", but I don't think it's technically "required". If there was an option for "Very useful and important, but not technically required", I would have selected that. Would be helpful to talk about what it means for HTML or CSS to be valid and how a validator works. I am still a little confused about the testing accessibility section. I would like to learn how to use validators. I'd like to get more used to writing out html! The anatomy of a URL and why it breaks down the way it does / URL anatomy, specifically the fragment piece How to see caches in your browser I'm curious where else this course encounters the topic of accessibility. Since we're building websites this is important to consider, and the reading introduces us to WAVE as an accessibility resource. Are there other lectures where we discuss accessibility when designing websites? Forms and how to make them accessible. I feel I am still a bit confused about the concept of URL and Caches; it would also be really helpful if we could go over examples of CSS layouts in class together! Apache, cache, I also don't know HTML and CSS so things were slightly more difficult to grasp I'm not completely sure what Apache is yet and why it is different from Flask. I don't have specific requests, I am pretty familiar with HTML/CSS
