Can anyone explain the weird presentation behavior in the UI screenshot above? As you can see, there's an undesirable separation between the insurance type and the top of the row. When looking at the code via Firebug, there's a clear break in the code. You can view this oddity in the code screenshot below.
The div.insurance-type parent container has no CSS styles. In other words, the vertical-align property, the margin-top property, the padding-top property, and the float property are set to default values and don't inherit a value that might cause this presentation. The children divs have this style:
div#worklist table tr td.col-InsuranceType div.insurance-type div {
display: block;
margin-bottom: 2px;
margin-left: 25px;
}
The span.insurance-company has this style:
div#worklist table tr td.col-InsuranceType div.insurance-type span.insurance-company {
font-weight: bold;
}
The components of this web app are:
ASP.NET MVC 3
Razor View Engine
jQuery 1.5.1
SQL Server 2008
IIS 7.5
This issue occurs in FF4, IE8 and IE7. Please let me know if you know the root cause of this unexplainable presentation behavior.
Thanks.
This is just a guess since I can't see the actual page, could there be some garbage character between the td and div that even firebug has trouble displaying? If the content is not client-side generated (ie: via Ajax), try viewing the source in Firefox (Ctrl-U or Cmd-U) and see if there is any weird character in there. I would even go as far as looking at the raw data in Fiddler.
On a different note, <div class="bold"> is bad practice (not semantic), use <strong> instead. :)
This might help:
Understanding vertical-align, or "How (Not) To Vertically Center Content"
Instead of
<div class="insurance-type">
<div class="bold">
<span class="insurance-company"
have you tried:
<div class="insurance-type"><div
class="bold"><span
class="insurance-company">

This is my first time posting here and I'm entirely self-taught, so bear with me please if I misspeak or say some dumb things.
I have a Wordpress blog. For quite some time, I have had my blog post format set up so that a "header image" displays across the width of the content space. Across the bottom of that image, I list the title of the post and the date.
To do this, I created what I believe is called a class -- I named it "container" and the only defining trait of this class is that it has "position: relative;" inside it's brackets. (It also has a "shadow" border. I tried taking this out and it had no effect.) This was done in the "additional CSS" section of the wordpress site.
.container {
position: relative;
box-shadow: 1px -1px 7px rgba(0,0,0,0.8);
}
I also made a class called "text-block" that is defined as follows:
.text-block {
position: absolute;
bottom: 0px;
right: 0px;
left: 0px;
background-color: rgba(128,128,128,0.6);
color: white;
padding-top: 10px;
padding-left: 10px;
padding-right: 10px;
padding-bottom: 0px;
}
Each post begins with opening a container. Then, immediately inside of the container is the image, with the width set to 100%. Then, still in the container, I put the text-block in, which is oriented across the bottom. The background color is opaque so that you still see the image behind the text, slightly greyed out.
Here is the code that begins the post of which I've attached a screenshot:
<div class="container"><img class="aligncenter wp-image-8056 size-full" style="width: 100%;" src="https://*mysite*/wp-content/uploads/thx-1138-film-confession.png" alt="Robert Duvall as THX 1138" width="831" height="364">
<div class="text-block">
<h2 style="color: white;"><em>THX 1138</em></h2>
<h6 style="color: white;">Review by *me* | November 6, 2020</h6>
</div>
</div>
The crucial part that I need to ask some advice on is the bottom edge of the container. Until recently, the bottom edges of the image, the text-block, and the container all coincided. Now, instead, a small amount of excess "padding" was added to the bottom of the container. So now, the text-block overlaps the image and some un-filled space beneath it, as you can see in the image. I can't seem to attach a second image of what it should look like, but I think it is clear what I'm trying to achieve.
I don't know where this excess "padding" came from. I didn't change anything -- no CSS was changed. I was just writing individual posts, copy-pasting the format from an old post to a new one to get the correct formatting. I was previewing a single new post when I realized the change, and I thought that I had messed something up on that individual post. But then I started clicking through my site and realized every single post now showed the error.
In the past, some other weird formatting things have happened that stemmed from a plug-in. I've deactivated all plug-ins and the issue remained. I've taken the text-block out entirely and the excess "padding" remains.
Like I said, I'm self-taught. I've really only learned things as I needed to know them. So it's possible I'm missing something simple or committing some grave error without knowing it. But it seems to me that my container lacks the definition that would cause it to be larger than an exact fit to what I put inside of it. Further, the fact that I did not change any of the underlying definitions seems to indicate it's some other kind of issue. But I don't know where it could be stemming from.
I would appreciate any help to figure this out!
UPDATE:
First, Akhilesh, thank you for the reply. Your suggestions did not directly lead to a solution but they at least got me into the spirit of trial and error.
I have found two "solutions" to this problem.
The first is to set "line-height: 0px;" inside of the container in "Additional CSS." This isn't ideal because it means that I can't type regular text in this container anymore. Not very elegant.
The second kind of seems like a fluke. As I showed above, my posts begin with:
<div class="container">**here**<img class="aligncenter wp-image-8056 size-full" style="width: 100%;" src="https://*mysite*/wp-content/uploads/thx-1138-film-confession.png" alt="Robert Duvall as THX 1138" width="831" height="364">
That is a single, unbroken line of code. By starting a new line where I indicate above, it solves the issue. As I stated in my initial description, I have not changed anything. All my posts have been like this since I decided on the format. And as Akhilesh stated, it works in the fiddler (which was a new tool for me, so thanks again).
So, problem solved, but what changed to cause the issue? Something in the way that Wordpress interprets HTML code?
Try adding this to the img element : display:block;
Also, try to find whether there's any padding/margin set for the h2 and h6 elements.
Because I don't see any issues when I tried. Here's the fiddle: https://jsfiddle.net/vL80u1a2/
If that didn't helped, try using the Developer Tools in your browser. Just right click on the element and choose Inspect Element. Then when you select an element on the left side, all CSS would appear on the right pane. You can try trouble shooting for the padding using that Developer Tools.
Have a look at this for more details on how to use the Developer Tools: https://developers.google.com/web/tools/chrome-devtools/css
Today I was trying to create a dummy css rule for testing and investigation.
.dummy {
some-style : somevalue;
}
Ideally the class should have no visible effect. I want to be able to apply the class to elements but cause the least visible effect possible on any elements it is applied to. For example
<div class="dummy"> should look and behaves as much as possible like <div>
I did not want the class to be empty. Can anyone suggest a style that I could add to the class that would have the least visible impact when applied to a general html element? I can't think of anything completely harmless.
UPDATE: I wanted to add the style to some existing html. The reason was to use the style as a marker for diagnostic purposes. It would help me see when and where styles and stylesheets were getting loaded/cached and where and why some styles were getting overridden, sometimes by the browser defaults which seemed odd. At the time I didn't have exclusive use of the system I was working on so I wanted something that was going to be invisible to other users but I could see in Developer Tools.
UPDATE 2 : the html/css wasn't written by me and I didn't have my own environment in which to work. I was trying to investigate some problems in-situ in someone else's system. I had tried using DevTools in the browser but wasn't getting anywhere with that. I wanted to be able to make some small changes to their html/css to aid my diagnostics. I didn't want them to have any obvious effect on the system for other people (except in DevTools, viewed by me).
It was a Wordpress site and they only had two environments, one for live and one for testing. I was working with the test system. There were other people testing at the time, though mainly checking content.
The real thorny problem was why was the font-size in the calendar widget much larger than everything else on the site? Inspecting using DevTools I could see the font-size style was getting overridden by the browser default style when it seemed to me there were other css selectors that should have taken precedence. It looked bizarre. In the end it turned out to be a missing !DOCTYPE tag in the html. So nothing to do with the css itself.
I didn't like this way of working, fiddling in someone's system, but there wasn't much else to do and it did help to resolve the problem for them.
Hopefully I don't have to do this again, but ever since I have been wondering what was the most harmless style that I could have used?
I thought I would ask here as there must be people who know CSS better than me.
You can use this:
.dummy{
min-width: 0;
min-height: 0;
}
If you just need anything beeing set you could assign rules that are default anyway. For block elements like div set
.block-class { display: block; }
And for inline elements like span
.inline-class { display: inline; }
Of course it could be an issue doing so in some rare cases but in general it's quite harmless I guess.
In principle, for any property you can have an arrangement like this:
div {
some-style : a-valid-value-for-some-style;
}
.dummy {
some-style : a-different-valid-value-for-some-style;
}
And .dummy's style will have an effect, no matter what some-style is.
Your best bet is to make use of CSS variables. These are custom properties and start with a double hyphen. so
.dummy {
--dummy-style: foo;
}
will make --dummy-style a property with value "foo". So long as you don't employ the variable as the value in another property, it will have no visible effect.
I'm specifically wondering about this page: https://podato.herokuapp.com/#/podcasts/http%3A%2F%2Ffeeds.twit.tv%2Ftwig.xml/
Why is the text of each item not alligned with the image on the left?
But a more general question: how do I debug this sort of thing? What's the best way to find out where whitespace is coming from?
For debugging you could use the built-in developer tools.
For official guides:
Chrome: https://developer.chrome.com/devtools http://www.html5rocks.com/en/tutorials/developertools/part1/
Firefox: http://www.howtogeek.com/105320/how-to-use-firefoxs-web-developer-tools/
https://developer.mozilla.org/en/docs/Tools
Also for Firefox i know there is Firebug, a tool developed to make debugging somewhat easier.
To answer your question, take a look at Vikas Kapadiya's answer, in your body tag is a line-height: 1.5; declared. Try and change it in the developer tools to see what happens.
Edit
A possible solution could be wrapping the span elements in a seperate div. I'm thinking of adding a negative top margin. Feel free to come up with other methods, this is the first one i think of.
The reason i'd choose for a div is because it is a block element, whereas span elements are inline elements, which are unable to add a negative top margin to. Also i noticed that you use a data-reactid? I guess it would be a bit cleaner if you could add that to the container div, so the span elements (and the br tag) are free of the data-reactid. Don't know if that is desirable, but see for yourself what would be best.
div.data {
margin-top: -5px;
width: 100%;
}
Try this in basscss line no 121
body {
line-height: 1;
}
So I have a simple page:
www.kensandbox.info/centerthis
This is a simple html/css page and I'm trying to add a paypal button.
The problem is that I can't figure out how to center the button? I've tried adding the following:
<div align="center"> form code here </div>
No dice. I've even tried adding the center tag before the form.
The site code (simple html and css file) can be downloaded here:
www.kensandbox.info/centerthis/centerthis.zip
My guess is that one of the other CSS elements is overriding my change.
What am I missing?
Thanks
there is a float:left in form input, form .btn inside mycss.css
Add float:none to that input if you want to override.
Without looking at your code I would say the best way to center a div is usually make sure it's displayed as a block element (should be by default) and that its width is specified; then finally apply margin: auto.
e.g.
<div class="container">
...
<div class="centered-element"> form code here </div>
...
</div>
where
container {
width: 200px;
}
centered-element {
width: 150px;
margin: auto;
display: block; /* to make sure it isn't being mucked up by your other css */
float: none; /* to make sure it isn't being mucked up by your other css */
}
Edit:
I say to do it this way because, like I now see someone has commented, <div align="center"> is deprecated and so is the <center> tag. To expand, this is because your HTML should only be used to create the structure and semantics of your web page, and CSS should be used for the presentational aspects of it. Keeping the two separate as best as you can will save you a lot of time in the long run.
Also it's best to design your CSS in a way where you shouldn't have to set display: block; on a div (because a div is already a block element) and your shouldn't have to unset a float by using float: none;. For more on a good way to do that, improve your workflow, save yourself some time, and generally be awesome, check into object-oriented CSS a.k.a. ooCSS
I found the answer and I want to thank the two individuals who took the time to answer.
The thing I didn't understand is how to look at a web page and see what CSS code was driving the formatting.
Some research lead me to a Chrome plug in named CSSViewer. Using this plugin and the information from the answer I was able to identify a float left css element that I simply had to change to a float center.
Thanks again for the help.
I've got an embedded widget from The Weather Channel and everything is working fine except that they've got a <tr> with a 1px height image that is expanding to a height equal to the other rows.
It's shifting the rest of the content down. Because it's just an embed, there is only so much of the styling I can control. But I figured it must be inheriting something from my stylesheet since it had inherited some line-height that I had to correct.
If you visit http://www.scwd.com and scroll to the bottom you'll see the weather widget. The row with the grey td below #weather.com is the issue. It should only be 1px in height. I've used multiple debuggers to see if I could find the inherit and I cannot. Any help would be great.
-- UPDATE --
Not the most elegant solution considering variable within the widget and out of my control may change in the future. But as David suggested, I solved it with the following.
<script type="text/javascript">
var x = $("img[src$='blank.gif']");
$(x).closest('tr').css('display', 'none');
</script>
Best I can find is:
Inherited from div#wx_module_6107.wow_container
.wow_container {
line-height: 14px;
}
Are you hosting this or pulling the HTML from a foreign source? I suspect you can't control the HTML that's being rendered or the CSS that it's using?
I'm no CSS expert, so thus far nothing I've tried in FireBug have made a difference without affecting the rest of the table elements in the widget.
Unless someone can give a CSS solution, maybe some JavaScript can get the job done? You should be able to, on document ready, find that img element (maybe by its src?) and from there (using something like .closest() in jQuery) find its parent td and parent tr and with those element references explicitly set their styles.
The image is in a td which has a line height of 14 according to your css:
.wow_container { line-height: 14px; }
I would give it a line-height of 1px and set the background-color to transparent. That makes things look nice for me. Is this widget coming from a wordpress plugin? If so which plugin? You may be able to edit the plugin code yourself.
I think the problem occurs because the font-size of the body. My suggestion is to add font:1px Verdana,Arial,Helvetica,sans-serif for the td that is the grey row.
