The content of the course is excellent. Descriptions are also excellent and very complete. The course has been created so that most people can understand what's happening here (even if you're new to programming).

I'm only giving this 4 stars because there are some things that make this course too slow, in my opinion. I don't think you need to mention which file we are working on [after the first couple of times] because we can easily see that by the name of the file and the browser of Sublime. Those are a few seconds that are a waste of time.

Secondly, I think that the questions in the practice questionnaires are a bit too easy. I didn't feel like they prepared me enough for the project at the end of week 2. You mostly ask if something is true/not which is too easy to guess. I think you would greatly improve the quality of the course if you designed some mini-situations. For instance (not sure if Coursera allows it), show a mini mockup and give 10 lines of code. Then ask how you will add another div to the top right of the mockup so that it aligns with the current code without breaking. Making those exercises not the same as your lecture code is going to help improve self-awareness. Currently, I think that people find it way too easy to select the right answer, since it's easy to remember what you said and what not.

I also understand that you wanted us to like the page for good reasons (because you look an extremely radiant and happy person) but I think you oversold it a bit. You should have mentioned that once or twice, but no more. Seeing it in a few of the examples wasn't quite my cup of tea.

On a good note, I was extremely [pleasantly] surprised when you did that real world project thing. That was an amazing idea and you're executing the details quite well (not writing 100% code on-screen, etc.). I really like how you sometimes say that we should look up the reference by ourselves, since that's what most programmers do (I study CS and after 3 years, plus a 6 month internship at a big company, this can't be more true).

I'm definitely giving this a 5* if you fix the questions to be harder and a bit more different to what you said in the respective video. They should make you think. Also, some of them could be open answers, requiring you to recall classes/code by memory (or cheat by watching the video). It would be nice if the answer was in some reference, so people could learn to use that too.

Sorry in advance for my english.

Pros - Theory, presentation, organization. In general, the course is delivered very well, it is interesting to watch, the lectures themselves are delivered beautifully and informatively. A trip to a client is a very interesting move. Instructions for the tasks and in general all the material (main and additional) is very useful and well structured.

Cons - Partly material, tasks, difficulty level of some topics. Outdated technologies are used (which is actually logical, after all, the course is old, but during this time it has not undergone changes in accordance with the development of technologies), mostly bootstrap, but there are also many small points that are no relevant and teach bad code (iife). Tests that I would like to replace with tasks. Tasks that are too simple and few of them. There is also a problem with a jumping level of complexity and missing explanations to the code. It will be quite difficult for a beginner to master this course.

In general, I recommend the course for educational purposes with the possibility of skipping part of the content.

I think this course fulfills its purpose in providing a comprehensive introduction to the three basic web development components, and showing the ways they are implemented through a real project. The problem is that, from what I can tell, this course is almost 5 years old and there doesn't seem to be any kind of update or revision, many times I got errors or bugs in my test code while following the lectures, with no way of telling if I did something wrong or something changed in the implementation. Also, the coding assignments felt way too simple for the amount of content that was presented in each module, even without having a good grasp of the concepts it's easy to get a 100 since the comments basically hold your hand through the code.

In general, for someone like me who had basic knowledge of HTML and no prior experience with CSS and Javascript, I got what I expected and I feel much more confident in learning more about web development, but the course definitely shows its age, so there may be better options nowadays.

This course was great in terms of material composition and the lecturer! I learned a lot and will definitely recommend it to others. I'm also taking the AngularJS course, because I really liked this one!

On the down side: in my opinion, the assignments (especially week 3 & 4) could be more challenging, as the course is targetted at web developers, so people familiar with coding. I found them quite easy. I understand that the last assignment was aimed mostly at forcing students to view all the lectures or get familiar with the provided code, but doing something bigger for the assignment (or at least without such obvious hints) would be a nice challenge and bring more value to the certificate, I think.

Splitting week 4 into two with separate assignments is also worth considering, as there was a lot of material covered in the last week, in my opinion (but I may be biased, as I went through the last week in a hurry, because I was late with my assignment).

Cons: 'let' and 'const', which are important concepts of JavaScript haven't been discussed. Differennce between window and global isn't discussed but used interchangeably. Assignments of module 4 and 5 are most of the part easy, they could be made a bit harder. I felt that Ajax code could be made easier to understand. I gave extra 3x time just to understand the Ajax from other sources and then the ajax code present here.

Pros: Apart from all the cons mentioned above it is nevertheless a recommended front-end web development course for beginners. You will learn HTML, CSS, bootstrap, git(hub), JavaScript, ajax, http, a bit of jQuery, DOM, etc. Just an advice to the students: don't be afraid of using external resources to understand the concepts better, specially Ajax, document, window/global, Http requests, rest API and jQuery. w3schools and MDN are the go-to sites for this course.

I have already undertaken a primer course like this through Coursera but found this one to go into more of the specific terminologies and concepts at a granular level. I thought overall the pacing was good and the application to a real world application in the form of a restaurant website was helpful in grounding the concepts. I have marked the course down a star because some of the information relating to Bootstrap is now very much out of date. There are a number of elements that no longer function the same as the Bootstrap framework has moved on quite a bit (4.5 at time of writing) and this course has not been updated to account for those changes. I found the odd piece of javascript didn't function quite as it should as well, also probably due to the age of this course. I found the Week 5 module quite difficult but would say I've learned a lot from this course.

This course is a very good introduction to web development, and for a good reason too. It covers a wide range of topics and concepts in a short time. I don't think it's suitable for a total beginner in programming.

Sometimes it felt overwhelming - trying to keep up with the instructor's pace. I couldn't finish the course in five weeks, by the way, although I studied every day. That's because I felt I didn't have the chance to practice coding enough, and I tried to practice on my own.

If I may suggest an addition to the course, it'll be some scattered tiny coding exercises in the quizzes maybe. I believe this will give learners more confidence and help them to test their knowledge and skill.

This is a very good introduction to HTML, CSS and at some extent to Javascript.

The first two topics were very well explained in details. The classes had a good pace and every topic was made very clear. The exercises at the end were a good challenge that matched the level of the course and gave us that extra incentive to push a little bit beyond.

The Javascript part was a little faster than the previous two topics (HTML and CSS). If only one thing should be corrected at this course I'd say that the same pace should be followed for Javascript.

I'd definitely recommend this course as a great introduction and one of the best courses I've taken at Coursera so far.

The class is very well put together and the instructor does a great job explaining things. I enrolled in this class just to see how things worked on coursera and wanted to do that with a simple starter style course.

Personally I think that this course should have stayed away from ui-toolkits and js frameworks (maybe just using something like normalize.css or reset.css). Maybe going into more things like @imports and writing maintainable html. css, and javascript. Anyway, it is minor i guess because in the end you still had to do some overriding of styles so you did write some of your own css.

All-in-all it was a fun first course for me on coursera.
