  1. Hello - first time posting. I've searched the forums to see if anyone else had the same question, with no luck. I'm going through the lessons in the tutorial but I can't figure out what's going on in part of the JS Type Conversion lesson. I'll link to the full lesson here, but below is the part I'm having trouble with: (mainly the function) I have no idea what's happening in the function... could someone be kind enough to break it down in detail for me? I understand how arrays work. But the function here has me stumped. Thanks so much
  2. Hello everybody I recently found this simple Image Hover Effect on w3schools: Image Hover Overlay: https://www.w3schools.com/howto/howto_css_image_overlay.asp This even seems to work on mobile (iOS) devices (touch), as far as I could test in the tryout editor. I then saved the provided code and published it on my own hosting (https://hammermann.ch/test.html). It's still working on desktop, but not on mobile (and I haven't changed any code at all) Any Ideas how to solve that? Thank you and stay healthy! Pascal
  3. Hello dear, i found one of your websites about the switch case statements in C++. https://www.w3schools.com/cpp/cpp_switch.asp It says: "If there is a match, the associated block of code is executed." This is not wrong, BUT it is not mentioned later (break statements), that the code ist executed *from the line* of the match (and not only the match codeblock) to the end of the switch block, if there is no break statement. "break" does not only save runtime, if you don't use it, you will get some hard to find unexpected behavior in your programs. Example: int i= 7; switch (i) { case 5: cout << 5 << endl; case 6: cout << 6 << endl; case 7: cout << 7 << endl; case 8: cout << 8 << endl; case 9: cout << 9 << endl; } Output: 7 8 9 Greets
  4. Found these sites when I searched for w3schools in Google: Are they related anyway to w3schools? They are creating confusion by using similar domain name. 1. https://www.w3schools.in/ 2. w3schools.sinsixx.com
  5. @w3school info I'm a Revit and Dynamo user. I'd like to learn Python and get the Certificate. My company wants to know how much time is all the studying, modules, and tests in order to go through everything you have and get this certificate?I need total time investment ranges and broken down by the sections (ex. 1 lesson section stopping points).
  6. Hello everybody, I was playing with a template from the w3.css templates from w3 schools and found an issue that I can't get around. In the template called Parralax template or the forth one from top, with the man with grey hat, I saw that the home screen image was loaded from the css .bgimg-1{ min-height: 100%; background-image: url(/w3images/parallax1.jpg); } (from the style brackets after the head tag ) I wanted to do a transition between two images but only found examples on the web that it is possible only when the image is loaded from an html image tag, so I removed the "background-image" from the above css code and added an <img src="/w3images/parallax1.jpg"> tag under the div where the class name was bgimg-1: <!-- First Parallax Image with Logo Text --> <div class="bgimg-1 w3-display-container w3-opacity-min" id="home"> <img src="/w3images/parallax1.jpg"> <div class="w3-display-middle" style="white-space:nowrap;"> <span class="w3-center w3-padding-large w3-black w3-xlarge w3-wide w3-animate-opacity">MY <span class="w3-hide-small">WEBSITE</span> LOGO</span> </div> </div> However, the image now has an empty white space from it's right side and I can't make it full. Does anybody know how to fix that?
  7. WONDERMENT: In anticipation of my next question while I continue my struggle with the implementation of optional key and button functionality on my own website, I thought that it might be helpful to bring the following to your attention. https://www.w3schools.com/CSSref/playit.asp?filename=playcss_overflow-y&preval=scroll QUESTION: Is there a good reason why the scroll bar does not appear when the [scroll] option has been selected? Roddy 🙃

  10. Hi! I've been learning HTML with w3schools and I really like it! Is there a version of w3schools in pdf format? Thank you!
  11. I am looking for assistance with my accordion code shown below. It functions perfect, but I am trying to get it so that when a panel is clicked and opened, if it is clicked again it will also close. I also want it to still close if another panel is clicked and opened, which is already working great thanks to you. <style> button.accordion { background-color: #262624; color: #f98100; cursor: pointer; padding: 18px; width: 100%; border: none; text-align: left; outline: none; font-size: 18px; transition: 0.4s; font-family: Playfair Display; } button.accordion.active, button.accordion:hover { background-color: #ffffff; } button.accordion:after { content: '\002B'; color: #f98100; font-weight: bold; float: right; margin-left: 5px; } button.accordion.active:after { content: "\2212"; } div.panel { padding: 0 18px; background-color: #f98100; max-height: 0; overflow: hidden; transition: max-height 0.2s ease-out; font-family: Playfair Display; } </style> <button class="accordion"> 1. What is paint protection film? </button> <div class="panel"> <p> Clear-Bra paint protection film is used to protect the integrity and beauty of your vehicle's paint finish. The 8mil (.008") clear urethane film adheres to the vulnerable painted areas of your vehicle (ie. hood, fenders, side mirrors, grille, front bumper, etc.). Saturday's primarily uses Xpel Ultimate and the new Suntek Ultra film which also comes with a 10 year warranty! </p> </div> <button class="accordion"> 2. Does it really stop rocks from chipping my paint? </button> <div class="panel"> <p> Absolutely! This product is used in many applications and was originally used to keep rocks and debris from damaging propellers on helicopters & the wings and noses of airplanes. It has been tested by engineers as well as Saturdays staff through years of experience. Of course if you hit a boulder you may be in trouble. </p> </div> <button class="accordion"> 3. What areas of my car will be covered? </button> <div class="panel"> <p> We can cover anything you'd like! From headlights, door edges, full hood or we can wrap and protect your entire car! Some vehicles have more impact areas than others. Generally we have a kit that will suit anyone's needs. From the basics all the way to full coverage. Saturdays has you covered! </p> </div> <button class="accordion"> 4. Is clearbra paint protection really invisible? </button> <div class="panel"> <p> It is very difficult to see the paint protection unless you are looking at it at the right angle under 3 feet away. Our patterns are computer cut and designed to contour to your vehicle's body lines. This will limit the amount of visible lines. Also, with full panel coverage package’s we wrap all applicable edges to reduce visible lines as much as possible. </p> </div> <button class="accordion"> 5. How long will my clearbra last? </button> <div class="panel"> <p> Our products are warrantied from 5 years to 10 years! Depending on how you treat vehicles can also play a role in how long the film will last. If you never wash your car, expect these products to not have as much shine in 5 years as a well taken care of car. We recommend washing your vehicle frequently and using liquid polymer wax on your entire vehicle at least 4 times a year. </p> </div> <button class="accordion"> 6. Do we wrap the edges? </button> <div class="panel"> <p> Of course we do! We are here to provide you with superior quality paint protection installation. A lesser shop won't do this just to save time. We wrap all leading edges where applicable. This gives you that extra protection that sets us apart. Only the best here! </p> </div> <button class="accordion"> 7. Do we polish and/or clay bar before installation? </button> <div class="panel"> <p> You betcha. We always want the paint perfect as possible before applying the paint protection. This process takes a little longer but it's definitely worth it. With no surface contaminates, your clear-bra paint protection will come out virtually perfect and "glass worthy". </p> </div> <button class="accordion"> 8. How long does installation take? </button> <div class="panel"> <p> Installation times will depend upon the complexity of the vehicle and the coverage you choose. This can take anywhere from 2 hours for the simplest kit to 72 hours for more complex or custom installations. We will be able to give you an accurate estimate when we know what coverage you decide on.. </p> </div> <button class="accordion"> 9. Do I need to do anything special to maintain my clear bra? </button> <div class="panel"> <p> There is nothing special to maintaining a clear bra. Wash and wax your vehicle as you always have, but stay away from paste waxes. These can leave a residue along the edges of the film and some colored paste waxes can actually dye the film over time. Stick with a liquid polymer wax when possible. </p> </div> <button class="accordion"> 10. Do you use a plotter to cut patterns? </button> <div class="panel"> <p> In the recent years plotters have become the new way to create patterns for cars. We offer both industry leading Xpel “computer cut” patterns as well as "hand cut" patterns for those custom jobs that other shops just can't handle. Whatever your needs are, we've got you covered. </p> </div> <script> var acc = document.getElementsByClassName("accordion"); for (var i = 0; i < acc.length; i++) { acc.addEventListener("click", accordion); } function accordion() { // Reset all of the elements for(var i = 0; i < acc.length; i++) { acc.classList.remove("active"); acc.nextElementSibling.style.maxHeight = null; } // Toggle the "active" class for the current item this.classList.add("active"); // Make the contents visible var panel = this.nextElementSibling; panel.style.maxHeight = panel.scrollHeight + 'px'; } </script>
  12. Hi, what is w3schools email address? office mail address, perhaps?
  13. I've just created a really simple online editor for HTML, Javasacript and CSS in "w3schools tryit" style. I call it WePro. The title stands for Web Programming, so, it doesn't mean I'm a pro developer. Feedback are welcome as this is one of my lesson in learning web programming. Please visit: WePro Hit "Run" to execute. The Code area is draggable and you can toggle it by clicking the "WePro title above the page. Is this any good?
  14. I'd like to know if i can download the most latest version of W3Schools, because in some areas where i live i don't always have good internet connection, so i'd like to be able to download the site to use it offline, but i've already downloaded early versions, but i want the most latest version.
  15. let's say i go through the tutorials from http://www.w3schools.com/Is there a way of knowing when some tutorial has been altered or updated ?Bcz I went through jquery mobile tutorial a year ago and a couple of months later, by accident noticed that there is new stuff in it.
  16. Dear experts, As we know that we can do so much with these great languages such as: tools, plugins, templates, applications, design/styles, etc. and even games. I think a little bit member activity will be great. Perhaps w3schools could add one more category on this forum, a place where members can share their creation (the small one of course). Perhaps some of you can even make some kind of competition (?) just for fun. It's not like I have creations to share, this just came up in mind. Beside, I only know some basics; but will learn to make some if there's a room for that.
  17. Hi, I can't find any other way of contact to say that www.w3schools.com is being blocked by SonicWall as a BotNet. IP Address is being blocked - see attached screen shot or look it up on http://botnet.global.sonicwall.com/view
  18. First of all,A BIG thanks to w3schools for teaching me HTML..But now I am getting interested in Ethical Hacking..There is no site in Milky Way like W3schools I know but still is there any site as close as w3schools that can teach me ethical hacking step by step for Free?!?!
  19. just noticed that some code I was having trouble with ended up not validating. http://www.w3schools...put_type_hidden this is some sample code to showcase the hidden input types If you put in this code <?xml version="1.0" encoding="utf-8" ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <form action="form_action.asp" method="get"> Email: <input type="text" name="email" /><br /> <input type="hidden" name="country" value="Norway" /> <input type="submit" value="Submit" /> </form> <p>Click on the submit button, and the input will be sent to a page on the server called "form_action.asp".</p> </body> </html> you end up with errors like this Line 6, Column 3: character data is not allowed here Email: <input type="text" name="email" /><br /> ? You have used character data somewhere it is not permitted to appear. Mistakes that can cause this error include: putting text directly in the body of the document without wrapping it in a container element (such as a <p>aragraph</p>), or forgetting to quote an attribute value (where characters such as "%" and "/" are common, but cannot appear without surrounding quotes), or using XHTML-style self-closing tags (such as <meta ... />) in HTML 4.01 or earlier. To fix, remove the extra slash ('/') character. For more information about the reasons for this, see Empty elements in SGML, HTML, XML, and XHTML. and a few of these Line 6, Column 43: document type does not allow element "input" here; missing one of "p", "h1", "h2", "h3", "h4", "h5", "h6", "div", "pre", "address", "fieldset", "ins", "del" start-tag Email: <input type="text" name="email" /><br /> ? The mentioned element is not allowed to appear in the context in which you've placed it; the other mentioned elements are the only ones that are both allowed there and can contain the element mentioned. This might mean that you need a containing element, or possibly that you've forgotten to close a previous element. One possible cause for this message is that you have attempted to put a block-level element (such as "<p>" or "<table>") inside an inline element (such as "<a>", "<span>", or "<font>"). a few more errors that might be due to the hasty page I created but things like the first bit really don't validate when you use them in a real context and teh second one. I've been able to get them to work if you wrap them in a span or div. Someone was telling me that input can't be a direct child element of form but has to have a block level element above it.
