      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.

Use   for small snippets of code Use   for lengthy snippets of code Use   if your snippet is HTML (optional) Use   if your snippet is SQL (optional) Rules of Conduct   Be nice. 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~

CSS Media Rule and Flexbox Dysfunction

Recommended Posts

iwato    6

BACKGROUND:  I have recently created a new page based on code used on another page that appears to be functioning well.  As the content is different, however, it was necessary that I make several important modifications.  Still, the basic format is the same, and I do not understand why the new content is not responding as it should.  As always, I have tried a variety of experiments before coming to you including resetting the values of the width property of both the media rule and the media rule's content, reordering the script order of both the imported CSS files and their content, as well as the placement of the CSS rules that command the flex-box.   My CSS selectors appear to be appropriate as I am able to generate change.  Unfortunately, the desired change is not the change that I am generating.

QUESTION:  What is the most likely cause of the dysfunction?

ORIGINAL PAGE:  Observe the behavior of the pages navigation bar, main section, right sidebar, and footer as the size of your viewport expands and contracts.  On my devices (iMac, MacBook, and iPhone) the behavior is the desired behavior.  The various section appear to function well no matter the selected browser.

NEW PAGE:  Although the main content section is empty, the right sidebar does not function as intended under the second media rule -- this, despite its proper functioning under the first and third rules.

NOTE:  I'll not place any code as everything is easily viewed online.

If it would encourage a response, I have since cleaned the file of potential noise that could have been getting in the way.

Thank you for responding.  I was beginning to think that no one cared.

The result of the second media rule should be the same as the third.  As the viewport contracts the column simply shifts from the right of the main content to below it.  When it moves below it should turn into a row that wraps, as it finally does well all parts of the document are stacked on top of each other.

But the direction is set as column, so that is why they stack above each other, as a COLUMN.

The direction is set as column only for the first media rule.  For the second, and therefore the third as well, the direction is set to row.  Take a closer look at podcast_template.css.

I know that! But that's the only one that looks odd? The others works as I would expect? they shrink to content, I.E the image, and wrap only when there combined sizes is greater than parent container width (- padding if any).

Yes, but what could be preventing the column of images from becoming a row, when the right column no longer fits in the viewport and is compelled to align underneath the left an middle panels?  What is more, why would the column switch to a row only when the header, left panel, main content panel, and right panel are aligned vertically, and not before?  After all, the row setting is occurs with the second media rule.

The combined width of the left navigation panel (200 px), main panel (504 px), and horizontal margins (10 px) is 714 px.  The second media rule should kick into effect as soon as the viewport reaches a width of 700 px.  Notwithstanding, no matter the size of the max-width, be it above, below, or exactly 714px, the result is the same.

What is more,  there is no CSS below the rule that obviously affects the size of the viewport or the panels in question.

I simply do not get it.

1st media rule

The child dive elements are still doing what block elements do,  fit to the width available to them, and using column just reiterates this, full width and stacked as column,  no bunching together or wrapping will take effect anyway because it is direction of column and not a row. The Images will just be a 150px width inline element on the left by default of full width parent element div.

2nd onwards produce wrap row version

Note the body element has a default margin of approx 8px, also scrollbars appear just before 1st media rule kicks in, meaning the combined width of left, middle, right etc exceeds 1st media rule width of 980px.

To test when media queries kick-in use identifiable background-color: for body element on each.

Got it.  Dsonesuk, you are one very knowledgeable individual.

It turns out that the 2nd and 3rd media rules were absolutely useless with regard to the desired flex box effect, and as you wisely suggested the column direction setting is completely unnecessary.

For others, however, you might wish to direct them toward Firefox's Responsive Design Mode.  For in this mode the screen width is counted for you, and you can watch the behavior of the window's contents as the width is being counted.  What is more you can set the width in the same window mode to the precise location that the change needs to be made.  It is a super tool; for it taught not only where the changes were taking place, but also where I needed to place the flex box display property to attain the desired affect.

(Firefox / Tools / Web Developer / Responsive Design Mode)  

Have a great day!

Roddy
