On the pages of many modern web services (including stackexchange webpages), there is a black header. What is the psychological effect of this? Is there any significance of it being black? Is there an optimal width for this header?

Been reading about . It's funny that ReadWrite, as well as StackExchange, has chosen a dark navbar as well.  Why this trend to choose dark navbars?

Why do we still have these HTTP error codes?  For me it seems like they are completely useless for the user (not for all but  most of them). It says nothing helpful (look at the screenshot above, it even doesn't says it's "an error") and explains nothing so I believe users are confused. And AFAIK it's a common way of representing HTTP error codes.  I believe browsers (for example) could handle these things somehow so original message will still be available for technical purposes but users will got more value.   So why they are still here? Is it possible to handle these codes more gently?  Update: why these errors could not be handled by the browsers? Or maybe there are any limitations? Incompatible design doesn't seems to be a problem for me, and I'm sure that standard views will improve UX because of similarity (errors will look similar for every site). And now I have to parse every cool designed error page to understand that happened.

As Google and other search engines keep trying to get more and more 'human' in terms of understanding what's good and what's spam, is it known if they take into account the size of a heading ie. an  thats font size is 40px is going to speak a lot more to the user than a  thats font size is 14px?  Similarly, does placement of text factor? E.g. a 300-word article at the bottom of a landing page (not in the footer but below the useful content) would be there just for seo purposes?  I know they look at things like text-indent:-9999px; and white text on a white background, but what about these more border-line practices that both have legitimate uses, but also the possibility to be spammy?

So when you use the comment shortcut C, you get the comment box appearing. However, you will get a weird black box.  Here's a picture of before:           And afterwards:           And after reloading, it disappears! This seems weird.  And after looking at the HTML, this seems to be the problem:  &lt;div data-questionid="260187" id="question" class="question keyboard-selected"&gt;   After removing the class attribute, the box goes away.

Alternative and much more boring title: Should a 404 result reveal the post title?  I ran across some odd behaviour today. When manually entering a Stack&nbsp;Exchange URL into the address bar1, if you pick a post number that has been deleted then you still see the old post title along with the 404.  For example, I entered:   http://webapps.stackexchange.com/questions/34 and the resolved address came back as http://webapps.stackexchange.com/questions/34/what-is-the-best-empire-avenue-stock-to-buy And http://stackoverflow.com/questions/3 came back as http://stackoverflow.com/questions/1/where-oh-where-did-the-joel-data-go/3#32   Note, I'm obviously not a 10k+ user on either of those sites, which is why they 404'd  It's not that big of a deal, but it seems like this leaks information about the site(s) that we may not want exposed.  And since a picture is worth N words:   Stuff I probably shouldn't be able to see is highlighted.  1And why was I manually entering posts like that? Because I was trying to find a benign 404 example from  that I could share with others because I think their 404 image is hilarious.  2And where did this fabled Joel data go?  Inquiring minds want to know!

The new fad is to place background images behind text. Best practice guidelines say it's important for the image to be relevant to the content. From a usability point of view, the content is less readable. You see this happening a lot on apple.com.  I'm curious what the big guys like the NN/Group would have to say about this. Bad for usability, marketing guys want it... worth it? I'd like to hear your thoughts.  And thank you to the mods who want to call this question a duplicate, but I'm talking about text on top of background images. The other question on this talked about color consistency affecting contrast. Thanks for your consideration.

I was working on a userscript today, which had a goal of displaying chat pings immediately at the main site. This would allow me to respond more quicker-like to chat pings.  However, I was met by this fearsome warrior:     Can we please set some decent header things? I want to be able to do this really bad.

Update: this change is now live across the network. You'll still see some narrow 220px ads because it's going to take us a good while to update all of the old ads, but if you see any other style issues, please report here on meta.   Stack Exchange sites are ad-supported. We run relevant, unintrusive ads that don't get in your way--but they help us keep the lights on. Even sites that don't have paid external ads usually have a few internal ones, used to promote other sites on the network and . We don't run a lot of ads, and , but the ones we do run have one crippling problem:   The sidebar ads are currently a weird non-standard size. Yes, standardized ad sizes are . And apparently if you ignore them, folks are more reluctant to advertise and have a tendency to make uglier ads. We don't like ugly ads, and we do like selling ad space. So starting next week, we will switch to the industry-standard size for sidebar ads. The new ad units will be 300x250 and the sidebar will be expanded to 300px wide to accommodate them. We won't be reducing content size or doing any sort of weird overlay; the ads and other sidebar content will just extend an additional 80 pixels to the right.  However, even though the sidebar is growing by 80 pixels, by reclaiming some margin space, the overall page width is only increasing by 60px. Here's what it's going to look like:     of Stack Exchange users won't be affected by this change. Either they already use a viewport big enough to accommodate the new width, or they already use a viewport too small to accommodate the existing width. (And those who do find themselves affected won't be losing any content, the juicy stuff we all come here to look at. They'll just see a bit of the sidebar cut off unless they scroll.)  We're planning to roll this out on Tuesday, January 12. (There will be a transition period after that date while we work on getting all ad types swapped over; you'll still see some of the old size ads during that time.) In the meantime, let us know your thoughts.

I want a header similar to Microsoft word that appears at the top of each page. However I do not want this on the first page. I would like to have the name of the project on the left, my name in the middle, and the date on the right.   What packages and commands will create a header as described above? What approaches can I take to customize the header?

Update:  Thanks for all the feedback and bug reports! I am locking this thread so people don't keep answering it when we no longer monitor it.  If you see a bug or want to raise a feature request, please do so in the usual manner, as a new question.    Some of you may have noticed that  the  and  pages that we have been talking about for a while now on .  Most? Well, yes, the new design is dependent on a SE network-wide update (a new base css framework) that the design team have been working on. This is an ongoing effort and we will be launching the new pages as sites are moved to the new design.  You've all been hugely helpful already - much of what we love most in here came from  and  you gave us on Meta.     But it's possible that it's not quite perfect yet. If you find any bugs and have any feedback to give, please post these as answers to this post.  Just post one issue per answer - that would help us focus on specific items one at a time.

I am using geoserver to serve up an image pyramid basemap.  I want to have all areas outside of the data extent be black (instead of white).  I have the map displayed inside of a div tag and changing the css on that tag or the container (another div) it resides in has no effect.  I have checked both the geoserver and openlayers documentation, but have not seen any way to change the background color.  Any suggestions on where to continue searching?  Do I need to generate a black tiles and serve them?

If you hear about Stack Exchange from a random person, and you’re thinking     Oh I want to go check out this nifty site kids these days like   you probably will open up your phone’s browser and look up stack exchange. However, the top link is, logically, to . No problem here, right?  Wrong. On my iPhone 7, this is what it looks like:    This is the first page a user will see if they look up Stack Exchange. While it’s a different question how well the homepage works on desktop, it’s a very bad first impression on mobile, especially compared to the lovely responsive design seen on the most frequently viewed pages.  This page is desperately asking for a responsive design, or at least a mobile version.

It would be nice if backticked code in question titles were rendered the same way they are in question bodies. Since there are so many questions with code in them I feel it would be a big plus. .  This would look a lot nicer in listings and on the page itself if the code strings were rendered as such.  Similar ideas discussed .

Here is an excerpt of the four most recent entries in my flag history on :    It seems like questions have a larger font size than answers (for no apparent reason) and removed posts are shaded (why is that?).  Here's a similar view on :    ...and on  where the alignment is off:    Since , something is still amiss here. Can this be fixed to be consistent? As an example, match how questions and answers are listed during  with a Q: or A: prefix (for a Question or Answer). The current visuals are not intuitive.

&lt;div class="subheader"&gt;         &lt;h1&gt;         &lt;/h1&gt; &lt;/div&gt;   .subheader has style border-bottom: 1px solid #e4e6e8;.  The bottom border should be below the whole title (I guess, the point is to separate the whole title). But the height of this div is hardcoded height: 40px;.  Shouldn't it be like this? (the screenshot with height: 80px;).

I'm looking for advice about favicons and their impacts on search engines. Recently I noticed a site which changes its favicon every time you load another page without losing overall recognition of the favicon style. I'd like to incorporate this into my site as well but am I taking any SEO risks here?
