I have a little problem. At the end of my R script I create an image .png as output. I wanna show this image on my website but sometimes it is drawn, sometimes it is not drawn. I don't understand how it is possible. I`ll put my code:
I insert the image in a div with this features:
#diagramm {
position: relative;
border: 2px solid #333;
border-color: #6495ED;
width: 820px;
height: 370px;
margin: 2px auto;
margin-top: 2em;
background-image: url("/home/daniele/public_html/appweb2013/venn_final/fungo_final.png");
}
Where is the mistake? Can I use a better method?
This is CSS, it only puts specific design rules for an element that has the id diagramm.
So what you've posted is not code so to speak.
In what way do you generate the output? When? what does the user do to generate it etc.
Do you have any javascript or html code you can show?

Hi I've been trying to create a smart button menu set in an drupal block that remembers which button has been clicked (which site it is on). For reasons that don't matter, it is not a menu it's an in-block item. I created the following in-line:
<div>Overview</div>
<div>Instruments</div>
<div>Travel</div>
This coupled with the following css produces lovely buttons:
.button {
background-color: #61210b;
color: white;
float:left;
padding: 2px;
border: 2px solid #000000;
border-radius: 5px;
text-shadow: 1px 1px #000000;
text-align: center;
text-decoration: none;
display: inline-block;
font-size: 16px;
font-family: 'verdana';
margin-bottom: 10px;}
.button:hover {
background-color: green;
color: white;}
.button:focus {
background-color: green;
color: white;}
.button:active {
background-color: green;
color: white;}
So everything above works great. However, the green activation color does NOT stay. As soon as I go click it goes back to what it was before. I want it to 'show' the page it is on with it's color change and only the currently chosen button will have the green color. What I have not works great except for that little issue. I've read around on the site a bit and here are some things that do not work:
--> inline php, creates errors link unreadable, if I define a class as selected with a different color, this does NOT work:
Overview
What also does not work is defining an additional class in the <a href > or <div> to make it 'selected', at best if I use the css file and do
.selected a { color: green; }
#selected a { color: green: }
I can permanently change the color to green, which is not what I want at all. I saw the discussion previously of using lists <li id="selected"> to create menues but not only does this not give me very nice buttons like my div format does, it also flat out does not work. See: CSS: How to change colour of active navigation page menu
The color just changes permanently, I only want it to change color if page=page of link. Since I'm using div this means I also cannot use the other pseudo-class-selector tricks like :target or :root. I have a feeling php is the way to go but I don't know why it can't be read in-line from my drupal box item. It has no problems with html or css in-line. Any ideas?
Try this code
CSS
.button:active, .button.selected {
background-color: green;
color: white;
}
PHP
Overview
what you wrote is calling for something else...
.selected a is targeting any element with the class "selected" which is inside an anchor tag, what you mean is an anchor tag which has the class selected = a.selected
ok, so I heard back from our system administrator and Drupal safety settings do not allow for in-line php or java scripting. There is literally no way to do this with div statements. The only way is to delete everything and make a new block of type menu block. In a menu block the psuedo-class :active will stay active if you use css
li .active
otherwise you can try to get php enabled but most drupal areas do not allow that or java scripting (at least it's not allowed where I am).
I want my page's logo and articles to be in the center of the site. At the moment everything is on the left.
I just can't make it work.
For Example I tried to delete the wrapper and set margin-left:auto; margin-right:auto; in the logo's class. nothing works.
And for the posts i just don't know where to start. probably i would have to put everything in a container and make that central? (There should be three posts in a row, at the moment the theme stacks them up to the right screen border if you have a big screen)
Thank you so much.
EDIT: The Text align in the image class did the job. Thank you guys, question answered!
#logobild {
margin-left: auto;
margin-right: auto;
text-align: center;
}
That will do it for you :) Your header takes up 100% of the space, so the content inside has no fixed dimensions to center against. The text-align value assists with that.
Try:
#logobild {
margin-left: auto;
margin-right: auto;
text-align: center;
}
To center the logo you can do the following in CSS:
img {
display: block;
margin-left: auto;
margin-right: auto;
}
The img element is inline by default, which means your margin styles won't be applied to it. When it is set to block level the margin settings will work.
To center the articles I suggest you give a width to the container div like this:
#post-area {
width: 85%;
margin-left: auto;
margin-right: auto;
}
I'm not sure if that's the best way, but it seems to work.
I'm trying to make a clickable button by treating a hyperlink with CSS and adding a little icon next to it. Everything but one detail works great; namely the icons which are slightly offset from the text on the button. It looks as follows:
As you may see, the white icons (12x12px) on the buttons are slightly higher than the text, touching the CSS borders of the hyperlink, while the rest of the text does not.
I have tried every solution that came to mind, including applying vertical-align to the image elements (which put the icon too close to the LOWER border instead, reversing the situation), but sadly could not get it to just line up with the text in the middle of the element nicely. What should I do?
Code in question:
HTML example of a button:
<td class="headerlinks">
<img src="{T_THEME_PATH}/images/icon_mini_login.png" alt="*" /> {L_LOGIN_LOGOUT}
</td>
CSS of the buttons:
.headerlinks {
margin: 0px 0px;
font-size: 1.1em;
line-height: 200%;
}
.headerlinks a img {
}
.headerlinks a {
white-space: nowrap;
border: 1px solid #FAE000;
padding: 1px 4px 2px 4px;
border-radius: 4px;
margin: 0px;
background-color: #000;
vertical-align: middle;
}
Are you using a CSS reset? You can try the following one.
http://meyerweb.com/eric/tools/css/reset/
Also it's better to use a background-image for the icon, and set a position on it.
This should work if you add margin-top:2px; to the icon class. This number may need to be shifted by a digit or two.
This will work if you maintain the static font-size.
Wondering if anyone has a solution for this.
I would like to present an archive of thumbnail images oldest at the bottom and newest at the top. I would also like the flow itself to be reversed... something like this:
The page should be right aligned, with future images added to the top of the page. I am creating the page dynamically with PHP pulling image filenames from a MySQL DB. The catch here is I would love this layout to be fluid, meaning most PHP tricks for counting images and building the HTML accordingly go out the window.
Is there a way to do this with Javascript or even just CSS?
See: http://jsfiddle.net/thirtydot/pft6p/
This uses float: right to order the divs as required, then transform: scaleY(-1) flips the entire container, and lastly transform: scaleY(-1) again flips each individual image back.
It will work in IE9 and greater and all modern browsers.
CSS:
#container, #container > div {
-webkit-transform: scaleY(-1);
-moz-transform: scaleY(-1);
-ms-transform: scaleY(-1);
-o-transform: scaleY(-1);
transform: scaleY(-1);
}
#container {
background: #ccc;
overflow: hidden;
}
#container > div {
float: right;
width: 100px;
height: 150px;
border: 1px solid red;
margin: 15px;
font-size: 48px;
line-height: 150px;
text-align: center;
background: #fff;
}
HTML:
<div id="container">
<div>1</div>
<div>2</div>
<div>3</div>
..
</div>
CSS Flexible Box Module was made for this type of thing. See a quick example I whipped up: http://jsfiddle.net/c6QLC/2/ (look at this in Firefox)
Now the bad news: you can't really rely on it yet. Not only is the spec being rewritten, the current implementation doesn't support box-lines (which I did include in the example), which would allow the items to be in multiple rows as opposed to being overflow.
The new spec is being written into dev versions of some browsers, so it will happen. It's just a matter of time.
In the meantime, perhaps something like Isotope might fit your needs.
Should you want to check out the spec, you can find it here: http://www.w3.org/TR/css3-flexbox/
This can be solved with jquery masonry plugin. It's a bit like isotope but free of charge for private and commercial users.
Ok, so I'm trying to implement a sliding video thumb gallery linked to a lightbox similar to the home page of reason.com but I would like to do it in pure CSS if possible. I already have the code complete for the lightbox which is basically pure CSS with a javascript:void function linking thumbs to the lightbox.
My issue is that I plan on updating the videos daily since it is for an article database and would rather not have to capture the video thumbs for every video upon updating.
Is there a way to dynamically capture thumbs of videos with a PHP script and including the script in my javascript:void link that will display the thumb for my lightbox? I'm basically trying to find a work around for capturing and resizing the thumbs for all of the videos in my thumb slider because this would be increasingly teadious to do on a daily basis.
Thanks in advance for any suggestions!
CSS:
.black_alpha{
display: none;
position: absolute;
top: 0%;
left: 0%;
width: 100%;
height: 100%;
background-color: black;
z-index:1001;
-moz-opacity: 0.8;
opacity:.80;
filter: alpha(opacity=80);
}
.video {
display: none;
position: absolute;
top: 25%;
left: 25%;
width: 50%;
height: 50%;
padding: 16px;
border: 16px solid orange;
background-color: white;
z-index:1002;
overflow: auto;
}
HTML:
<body>
**I want each thumb to link to this** <a href = "javascript:void(0)" onclick =
"document.getElementById('light').style.display='block'document.getElementById
('fade').style.display='block'">
<div id="light" class="video"> **this should show the video of the thumb clicked**
<a href = "javascript:void(0)" onclick = "document.getElementById('light').style.display='none';
document.getElementById('fade').style.display='none'"></div>
<div id="fade" class="black_alpha"></div>
</body>
I thought the thumb slider would have been irrelevant so I didn't include it.
You can use ffmpeg to capture images from video. It's easy to use and just needs to be installed on your server. You can run the ffmpeg commands from php using exec() (note: this may need to be enabled in your php.ini)
