      Guidelines and Netiquette   03/28/2017

      Posting Problems:   Having problems posting your topic? Read through this: To join, you agree to our terms and conditions and fill out and submit a registration form. An activation email will be sent to your email adress, so you'll need to verify your account. After that the account has to be validated by one of the moderators. This will mean that it can take up to a day to be activated. A couple of things to remember to ensure approval: Don't use an email address in one of those $2 four character .com domains eg. xyds.com. These will be deleted and the domain added to the banned list. Don't use an email address that is within a domain with a bad reputation for spam. A Google search is run on every email address and email domain. Don't sign up with an email address that doesn't exist, doesn't work or requires the sender to answer a quiz before their email can get to you. Put your country and or state and city in the signup form. Blank forms will go to the botton of the "to do" list. And make sure that your email address and your country match, saying you're from Alabama and using a .ru email address is not going to get you activated. After a membership is activated the first few posts will be monitored. Posting spam or unapproved topics described in the agreement results in an immediate ban. The email provider and the IP addresses associated with the account will be banned and all posts will be deleted. These strict measures have been deemed necessary to hinder spam. Sorry for any inconvenience this causes, but it's not liable to change. If, after reading this, you still can't post and don't understand why, contact one of the Moderators listed here.   Topic Guidelines   Including the following information can expedite an accurate response from board members: Must be a Specific Problem or Question related to web design and development Include Code in Question (wrap with   for small blocks of code and for longer blocks   ) Include Code Author Include Extra Notes/Modifications/Attempts Include web link to page/file when possible Content Guidelines   You may not post, upload, link to, or email any Content that contains, promotes, gives instruction about, or provides prohibited Content.

There's no need for calling someone stupid if they ask an 'easy' question. Keep your avatars and signatures absolutely child friendly. We have a younger audience on this forum. Keep your language appropriate for the same reason above. Do not PM moderators for help on the forum. Post on the topic, or create a new one.   Spam:   Recently, as you have all without doubt noticed, we have had lots of spam and advertisement on the forum. Therefore, we'd like to alert you as to what to do when you have found any of the aforementioned annoying messages: it. Immediately. Give a clear reason, please, if the advertising is not evident. DO NOT POST! Report, let the post stay as is, and we will get to it, meanwhile if you continue to post as normal in the other threads, it won't be on the top so long. Refrain from PMing the member. This won't help at all, as they are most likely spambots anyway. Thank you.       Images in signatures:   After thinking of users on dial-up, we have decided to enforce the following rules regarding signatures. Please pay heed to them. Respecting these rules is respecting the members on this forum with dial-up. Signature rules: No animated images AT ALL. No matter the amount of animation. Maximum image widthxheight: 300x150 Maximum image (file) size: 15kb Use calm colors. Do not use highly contrasting images in your signature, as this can get really annoying when seeing several posts from one member in the same thread. The same prohibited content goes for images as for posts. Lastly, use common sense. No lengthy signatures please. Save us some scrolling. Thank you.       Links in signatures:   Please understand that w3schools.com only exists because of voluntary work and is barely supported by the advertising littered throughout the tutorials and the forum. So, please, stop advertising other sites. DO not post links that drive traffic away from the w3schools domain - especially to a site that offers similar if not identical information. Please help support the site by keeping individuals on it. Thank you. Here are some guidelines as to what you can put in your signature: w3schools links --> allowed w3.org links --> allowed browser links --> allowed html editor links --> allowed personal sites --> allowed tutorial sites competing with w3schools --> NOT allowed sites completely irrelevant to webprogramming and this forum --> NOT allowed   Thanks for understanding, and for taking the time to read this. ~W3Schools Modstaff~

W3 CSS Slideshow Indicators with two images?

Recommended Posts

jbs    0

Hello, I'm currently trying to utilize the W3 slideshow example shown at https://www.w3schools.com/w3css/tryit.asp?filename=tryw3css_slideshow_imgdots

The script works great, as long as I use all 3 image slots. As soon as I delete one and try to make it a slide show between 2 images, with two onClick images underneath, the two onClick images do not center themselves under the main image like when there's 3, and instead they float left. I've tried tweaking every possible variable in https://www.w3schools.com/w3css/4/w3.css without any success. 

The main parameters that seem to have an effect on the onClick images are the lines:


.w3-col,.w3-half,.w3-third,.w3-twothird,.w3-threequarter,.w3-quarter{float:left;width:100%}

.w3-section,.w3-code{margin-top:16px!important;margin-bottom:16px!important;}

.w3-row-padding,.w3-row-padding>.w3-half,.w3-row-padding>.w3-third,.w3-row-padding>.w3-twothird,.w3-row-padding>.w3-threequarter,.w3-row-padding>.w3-quarter,.w3-row-padding>.w3-col{padding:0 8px}

 

However no tweaks I've done seem to have the desired effect of centering the two onClick examples. If anyone could nudge me in the right direction that'd be greatly appreciated. Thanks for any help in advance.

This works for me:

<div class="w3-content" style="max-width:1200px">
  <img class="mySlides" src="img_nature_wide.jpg" style="width:100%">
  <img class="mySlides" src="img_fjords_wide.jpg" style="width:100%">

  <div class="w3-row-padding w3-section">
    <div class="w3-col s6">
      <img class="demo w3-opacity w3-hover-opacity-off" src="img_nature_wide.jpg" style="width:100%" onclick="currentDiv(1)">
    </div>
    <div class="w3-col s6">
      <img class="demo w3-opacity w3-hover-opacity-off" src="img_fjords_wide.jpg" style="width:100%" onclick="currentDiv(2)">
    </div>
    </div>
  </div>
</div>

Just change the s4 classes to s6.

Yea that definitely works. It does resize the onClick images to where they're much larger than when it's a row of 3. If that's the only way to do it no worries, just figured I'd ask if you could keep the original size but still have it centered. And thanks for the quick reply, I'll definitely use this if it's the only option.
