CSS - Dynamically Assigning Properties
I have a loop in PHP that runs through sets of data and assigns positioning based on its place in the loop. For some reason the styles for position aren't being applied.
Any ideas what i'm doing wrong? Code: <html>
<head>
<style>
#wrapper {width:100%; height:100%;}
#box {background-color:gray; width:100px;}
</style>
<body>
<div id=wrapper>
<div style="postion:absolute; left:50px; top:100px" id=box>AA</div>
<div style="postion:absolute; left:100px; top:100px" id=box>BB</div>
<div style="postion:absolute; left:150px; top:100px" id=box>CC</div>
</div>
Similar TutorialsI have a container DIV a with absolute position containing DIV's b,c,d each with absolute position. Code: <DIV class="a"> <DIV class="b"></DIV> <DIV class="c"></DIV> <DIV class="d"></DIV> </DIV> <DIV class="e"></DIV> DIV e has no asssigned position and is not displayed(floating in the background). I want to replace any of b,c or d (setting display to none) with e, displaying e in the position of either b,c or d. How do I assign the style of one DIV to another that is not its parent? I could if necessary place e inside a and do a swap, but I have quite a lot of DIV's like a, and would rather not have to repeat the code in each container DIV. Hope this makes sense! Hi people, I am completely new to programming and have only spent this weekend learning it! I have managed to create a decent website already, however i am stuck at a point. On my main page, i have attached a CSS stylesheet with all the formatting for my page. My problem however is that when i try to format one section (<div id="gallery">) the formatting messes with the rest of the page. Is there a way that i can assign a style sheet to only that <div id="gallery"> without it applying to the entire html page. Any help is greatly appreciated! Thanks Chris Hi All... New to CSS, forgive my ignorence... I have started using CSS to assign classes to form elements, this works fine with input boxes but has no effect when assigning the same class to a dropdown listbox "<select>" - no change is apparrent in their appearance... Can anyone help please? Is this anything to do with 'contextual selectors'? If so how can I perform what i want to do? Sample of my code... Title: <select name="CUSTTITLE" class="formelements" > <option value="" <?php if (!(strcmp("", $form->value("CUSTTITLE")))) {echo "SELECTED";} ?>></option> <option value="Mr" <?php if (!(strcmp("Mr", $form->value("CUSTTITLE")))) {echo "SELECTED";} ?>>Mr</option> <option value="Mrs" <?php if (!(strcmp("Mrs", $form->value("CUSTTITLE")))) {echo "SELECTED";} ?>>Mrs</option></option> <input name="CUSTFIRSTNAME" type="text" class="formelements" size="15" maxlength="40" value=" <? if($form->value("CUSTFIRSTNAME") == ""){ echo $session->userinfo['CUSTFIRSTNAME']; }else{ echo $form->value("CUSTFIRSTNAME"); } ?>"> .formelements { font-family: Verdana, Arial, Helvetica, sans-serif; font-size: small; color: #000000; margin: 1px; border: 1px solid #CCCCCC; } Any help would be appreciated. Thanks Arco Hi Everyone. I'm a new member and so please forgive me if I don't immediately understand all the jargon. However I have a problem and I was hoping someone might be able to help. I have searched the web and W3 schools but couldn't find the answer I was looking for. I am using strict HTML with an external CSS style sheet. I have a several paged website I am creating for part of a University assignment. I have several links which have 3 colours for 3 states. Link, visited and highlight. These work perfectly. (For me anyway). I have now been told to remove 'circular references'. I understand this to be; If I am on the 'Home' page, then 'Home' is no longer a link. (The cursor turns to a text bar instead of a hand) I have removed href from the html to stop this happening. leaving just <a>Home</a> This is fine, however, the colours that I specified in the css now no longer apply and the text is just black. I have followed the instructions in the web pages that I have seen to retain the colours, or add them to an inline style sheet, but nothing seems to work. I can only achieve adding one colour (but not making it change when visited or hovering) or changing the colour of ALL links. Sorry if this is confusing.. I hope someone can help! The relevent code is below. HTML <head> <style type="text/css"> .homebut a:link {color: red;} .homebut a:visited {color: purple;} .homebut a:hover {color: orange;} <!--none of the above seems to work--> </style> </head> <body> <div class="homebut"> <a>Home</a> </div> CSS /*This is applied to all links but doesn't work when I remove HREF from the HTML*/ a:link { COLOR: #0099FF; text-decoration:none;} a:visited { COLOR: #00FFFF; } a:hover { COLOR: #FFFFFF; } I'm trying to write a function that will resize a few <div>s on my page when it loads. Before I got too far, I wrote a simple function to alert the current height of each <div> to be resized. It looks like this: Code: function resizeDivs()
{
var saidDivs = new Array("cBodyMid", "cLeftPane", "cLeftPanelData", "cRightPaneData");
for(i=0;i<saidDivs.length;i++)
{
var el = document.getElementById(saidDivs[i]);
curElHeight = el.style.height;
alert(curElHeight);
}
}
All I get is 4 empty alert boxes. All of the styles are defined in an external style sheet a la: Code: #myDiv {
height: 25px;
}
and they are all assigned to <div> tags a la: Code: <div id="myDiv">here's my div</div> However, if I create a div with the height specified as an inline style, it works. I've got to be missing something really simple here. Anyone know how to get that height property? You know how you can modify Mozilla css with properties like css Code: Original - css Code -moz-border-radius: 4px 4px 4px 4px; -moz-border-bottom-colors: ThreeDDarkShadow ThreeDShadow transparent; -moz-border-top-colors: ThreeDDarkShadow ThreeDShadow transparent; -moz-border-right-colors: ThreeDDarkShadow ThreeDShadow transparent; -moz-border-left-colors: ThreeDDarkShadow ThreeDShadow transparent; -moz-border-radius: 4px 4px 4px 4px; Is it possible to get something like this to work with IE? See on F/F the box is rounded.. but on IE its just a complete square ( duh that's because I'm modding Mozilla css properties ). I see that document.getElementById('foo').style.width is a valid property, but yet I see documentation which accesses the style's properties as an array element, example: document.getElementById('foo').style['width']. Are both equivalent? What would be the property equivalent for 'text-align'??? document.getElementById('foo').style.textAlign?? Where can I find the docs for this? For a navigation I am using, I must use an li height to control spacing in IE6. I'm also using bullets to show a user where they are in the site by only having one bullet display at a time. Unfortunately, the height assignment I use on my li causes IE to misplace the bullet next to its secondary nav. Below is code I'm using to troubleshoot: Code:
<ul><li><a href="#">dog</a></li>
<li><a href="#">cat</a></li>
<li class="here"><a href="#">fish</a></li>
<ul>
<li><a href="#">trout</a></li>
<li><a href="#">angel</a></li>
<li><a href="#">salmon</a></li>
</ul>
<li><a href="#">turtle</a></li>
<li><a href="#">elephant</a></li>
</ul>
Code:
li {height: 20px; list-style-type: none;}
li.here {list-style-type: disc;}
If a user is on the page fish, they will see that bullet point to page salmon. Any recommendations? I have a style for links that I use in my main navigation menu, like so: Code:
a.main_nav
{
color:#FFFFFF;
font-size:12px;
}
a.main_nav:link{ text-decoration: none }
a.main_nav:visited{ text-decoration: none }
a.main_nav:active{ text-decoration: none }
a.main_nav:hover{ text-decoration: underline; }
How can I wrap all the links in a <div> and not have to specify the class on each <a> ? I noticed that if you place a border around an object with all sides having different colors, that a diagonal appears in each corner where the two colors meet. Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>My site</title>
<style type="text/css">
#my_id {
width: 100px;
height: 100px;
border-top: 10px solid red;
border-bottom: 10px solid green;
border-left: 10px solid blue;
border-right: 10px solid black;
</style>
</head>
<body>
<div id="my_id"> </div>
</body>
</html>
Is there anyway to override this so that for example the bottom border extends from left to right edge at a height of 10px (using the above example) instead of gradually decreasing the height as it nears the edge? Edited to add: I know that I could achieve this effect by nesting divs but I was curious as if there was a simpler solution. Hi! Does anybody have some great link or book advice about all the properties of the DIV and/or LAYER - tags? Inspiring examples with javascript to this are also welcome. I will use it to build advanced layer functionality. Regards Bjorn I am confused by the "rules" of how to indicate what you are trying to style when an element is within other elements. Specifically in this case (but hopefully this lesson will be portable to other contexts). I have a UL with an LI (classed) that is within an id'd UL that is within an id'd DIV. Code: <div id="horzmenu">
<ul id="horznavmenu">
<li><a href='rooms.php'>Accomodations</a></li>
<li class='hot'>Location & Info
<ul>
<li><a href='/otherprops.php'>Other Properties</a></li>
<li><a href='/news.php'>News & Photos</a></li>
</ul>
</li>
<li><a href='booking.php'>Booking</a></li>
</ul>
</div>
So if I were to wish to style this new UL and its LI's do I refer to: The parent UL as in: #horznavmenu ul ul { The parent UL and the class'd LI as in: #horznavmenu ul ul li.class{ Or? Thanks in advance for any feedback or suggested reading... I want the iframe to have a horizontal scrollbar but no vertical scrollbar. My code I've been attempting looks like this: Code: <iframe scrolling="auto" src="quicklinks.php" width="100%" height="200" name="helpContent" style="overflow-x: visible; overflow-y: hidden"></iframe> Is this possible? If so, is it compatible with all browsers? I know many of you are going to say, well you have it on auto and if you don't want it to scroll vertically, don't have a page in the iframe that is too high in height. However the page has dynamic thing submitted to it and there might be the possibility that a user submits a name too long and I don't want to deal with only showing a certain length of the string. Hey all, I'm developing an app for a client, and I've implemented quite a bit of it already, and it includes CSS. Code:
<style>
td {
font-family: Arial, Helvetica, sans-serif;
font-size: 11px;
color: #000000;
text-decoration: none;
}
</style>
As you all might know, this changes all <td> tags into this particular style. Is there a class that I can include that contains NO properties (default)? I'm not even sure if it's possible. I just don't want to go back and add class tags everywhere. Is it necessary to declare properties like : border-bottom:none; text-transform:none; My question is why would I declare them (above) ? Is it not assumed that unless I need something like text-transform:lowercase; I should not declare text-transform:none; ...this just add up more unnecessary lines of code. What are the default properties of selectors? if not declared would it be safe to asumme that those defaul to 0, none, etc depending of the selectors? tahnks Guys I have the following issue regarding links and colours: The colours of links are set thus: a:link : White; a:hover : Blue; a:visited : White; The problem I have is that I want a hovered link to turn blue even if it has been visited. Is there anything I can do about this...? Hullo, I have an issue here that I have been trying to find a solution for for the past week, but I suppose I don't really know what exactly to look for. I want to make a background that consists of different horizontal color strips. The reason I do not want to use an image and repeat it is because the strips are different in height. I want them to shrink/expand vertically keeping their proportion to each other ( instead of repeating vertically) in case the screen used to view the website is smaller/ bigger than mine. I tried creating different elements using <div id="name"> and assigning a background color and define a percentage for the height, however this doesn't work because the element has to have text inside it to expand according to it. I do not want to assign fixed heights because as I said I want them to expand and shrink proportionally. If you know a way to do this even if it is not CSS please let me know. All help is appreciated. Thanks. Hi does anybody know how to set a tables properties and also give it a class name in an external css so that when i import it i only have to state the class name, instead of all of its properties. Properties such as border color, background color, cell spacing etc Cheers for the help peeps Andy Hi Below there are three tables. first one is separated but the second one is inside the third one. Although I have set padding and border-collapse to collapse and padding to 0px but they don't appear the same size on the screen. table 3 is bigger than table 1. is there any property that I can set to 0 so table 3 appears the same size as table 1? PHP Code: <STYLE> table{ border-collapse:collapse; } td{ padding:0px; } </STYLE> <TABLE STYLE='background-color:red;width:800px;border:1px solid black;'> <TR> <TD> </TD> </TR> </TABLE> <TABLE STYLE='background-color:red;width:800px;border:1px solid black;'> <TR> <TD> <TABLE STYLE='background-color:red;width:800px'> <TR> <TD> </TD> </TR> </TABLE> </TD> </TR> </TABLE> I am having two problems with my tables right now: Within the style sheet, I have the following: table { border: thin #0000CC; } If I am not mistaken, this should make all tables that have a border of 1 or greater to automatically be thin and blue. This is not working... Why not? D |
