  1. By "not working" what do you mean? Does the frame exist? If so, what is inside the frame?
  2. The grammar is correct, slid is the past tense of the verb slide.
  3. Basically by counting pixels. A good image editing program will be able to tell you the coordinates on a bitmap. The issue with image maps is that they don't scale if you resize the image in HTML or CSS.
  4. There should be another <script> tag which loads the carousel plugin. Can you verify that it exists?
  5. This is not valid Javascript syntax, you can't have a literal value on the left side of an assignment operator. Maybe that's a thing in Node.js, but I don't have any experience with that.
  6. I'm not sure where you heard about this. If I had some context I could understand your question better. Most likely it means that PHP constant names are case insensitive meaning that "constant" and "CONSTANT" point to the same place. You can create your own constants using the define() function. PHP has thousands of built in constants, you will have to search the manual on php.net. Here are a few of them: String constants Array constants Math constants cURL constants
  7. I think minDate expects a string with a specific format. You just passed in a Date object. You need to generate a string something like this: minDate: dateMin.getDate() + "/" + dateMin.getMonth() + "/" + dateMin.getYear(), If that doesn't work, it's probably because you need to pad the day and month with zeroes on the left.
  8. I usually give the tag a max-width in ems so that regardless of font size it always breaks at the same place. This solution requires no change to the HTML. Add text-align: center and a left and right margin of auto to keep it all centered.
  9. Can you provide a link to the tutorial page?
  10. I am locking this thread as people are posting links to websites that violate W3Schools copyright.
  11. It's optional, I don't see a reason to use it.
  12. $row is clearly a string that begins with "r". You will have to show the code that is assigning a value to $row.
  13. Referring to C++ as a "blockchain programming language" is pretty inaccurate. C++ is not a programming language dedicated to developing blockchain applications, it is a general purpose object-oriented language designed to be close to the metal. I think you are mixing Java with Javascript, they are two completely unrelated languages.
  14. These are not issues, they are just suggestions of things that the machine couldn't not verify are good. As long as a human can verify that this is accessible you can just ignore these warnings. The first message "Link text may not be meaningful." means that the text inside the link should be meaningful even out of context. This message is in place because some people put text like "click here" and "this website" which are meaningless without more context. If you think your link text is meaningful then you can ignore this message. The second message "Anchor text may not identify the link destination." is shown when none of the words of the link text are found in the URL of the link. The computer thinks that this might indicate that the link text does not describe the page that you are linking to, however if you know for sure that the link text describes the target page then you can just ignore this message as well.
  15. getElementsByTagName does not return an array, that's actually an HTMLCollection object.
  16. That code uses <font> tags, <br> tags and alert(). It is a clear example of how not to write code.
  17. HTML without CSS is practically useless in the modern web. If you don't know CSS in depth then you might as well not know HTML. CSS appears simple on the surface but it is actually more difficult to master than many people think. If you intend to be a full stack developer, it is usually a good idea to master the front end before moving on to the back end.
  18. It is not easy. You will need to install a server on your computer and then use a server-side programming language to write data to a file.
  19. Your PHP code is calling an undefined function, so it's showing an error message which is not valid JSON.
  20. I tested on this page and there is enough space for the answer. There are three different text fields that you have to fill in, you can't just put the whole answer in just one of them.
  21. That's inside a string, so it's not python syntax, just text. Whichever library is using the string probably has documentation about its syntax.
  22. I'm not certain how frequently the staff visits the forum, but I'd say less than once a year. If you find an error on any page you can click the "REPORT ERROR" button at the bottom of that page to send a notice to the site owners.
  23. Sprites have limitations. For one, the container must be the same size in pixels as the sprite you're representing, otherwise other sprites on the same image are visible. Another limitation is that sprites cannot be repeating since background-repeat repeats the whole image file and not just a part of it. In short, you can't style a flexible box using sprites. On the other hand, you can use the border-image property in CSS to split an image into parts and use them to style a box.
  24. This sounds like a homework question. Have you given it a try yet?
