I am looking to present a set of properties. key: val type-of-thing. Not knowing any better, I am laying it out in a table.
The following css:
table.properties td:first-child {
text-align: right;
}
table.properties td:first-child::after {
content: ":";
}
aligns the text in the 1st column (the keys) to the right, then appends a semicolon.
Is there a way to express that in a more concise way? Like in a single rule? Or maybe such presentation is better done in another manner altogether?
Appreciate a tip!

I would like to have extra space before a header in the middle of my
document but not the first header at the top of the page.
That seems like it would be a common situation but I have to
manually specify it.
In other words. I want this
but if I specify
h1 {
margin-top: 1.83em;
}
Then I get this ugly extra space at the top
I get that I can fix it by manually specifying the top header. For example
h1 {
margin-top: 1.83em;
}
h1:first-child {
margin-top: 0.66em;
}
But I'm wondering if there is some other way(s) and what the tradeoffs are. I can certainly add a class or an id to the first header and change the CSS to use that class or header but I'm assuming this is a common pattern so I'm wondering if there are common solutions.
Use the :not pseudo class to define the style for all h1, but the first:
h1:not(:first-child) {
margin-top: 1.83em;
}
<h1>first</h1>
<h1>second</h1>
<h1>third</h1>
I am trying to have two different Font Sizes in the same Table th cell
My code is as below but does not appear to work i.e. the (Frm) stays at font 14
Please help
echo "<th width='70%' style='background-color:#FFD8D8;font-size:14px' colspan=\"14\"><left>".$startlocation."<style='font-size:8px'>"."(Frm)"."</left></th>";
There is no such element called <left>. What I would recommend you do, is add classes to your elements instead of using inline styling through style=.
th {
width: 70%;
background-color: #FFD8D8;
}
.left {
font-size: 8px;
}
.right {
font-size: 14px;
}
Then you can add a <span> tag around your text, which can look something like this as your final code:
echo "<th colspan=\"14\"><span class=\"left\">".$startlocation."</span><span class=\"right\">(Frm)"."</span></th>";
I'm not sure what your other text is inside the <th> element, but doing what I did will solve it. It's also best practise to use classes and IDs instead of inline styling, as it's easier to change in the future.
EDIT: If you absolutely need to to inline styling, this will work:
echo "<th colspan=\"14\"><span style=\"font-size:14px\">".$startlocation."</span><span style=\"font-size:8px\">(Frm)"."</span></th>";
Insert <span> like this:
...$startlocation."<span style='font-size:8px'>"."(Frm)"."</span></left></th>"
so that you can specify style of some element the way you tried.

Should css class names like 'floatleft' that directly describe the attached style be avoided?
I was wondering what the best practices were for the naming and usage of CSS classes.
For instance, in a scenario where you want to center the text of both the button text and the header text, is it better to repeat this style in both classes like
.button-text {
text-align: center;
/*some properties*/
}
.header-text {
text-align: center;
/*other properties*/
}
Or is it better practice to move that style out into a separate class like
.center {
text-align: center;
}
.button-text {
/*some properties*/
}
.header-text {
/*other properties*/
}
and have the class of "center" applied to elements that have the classes of "button-text" and "header-text".
What it comes down to, is, should CSS class names represent what an element is "button-text" or "state, what an element looks like "center"?
Thanks!
A CSS class should represent what you use the element for, not what the element looks like.
Consider that you have headers that are red and bold, and change the design to large blue letters instead. If you named your classes after the look of the headers, you end up with:
.RedBold {
color: blue;
font-size: 200%;
}
Having a class named center is definitely the wrong approach - this class name already implies the presentation, that's not the point of defining presentation in a separate file. A better way to avoid code duplication would be:
.button-text, .header-text {
text-align: center;
}
.button-text {
/*some properties*/
}
.header-text {
/*other properties*/
}
Another option is specifying multiple classes, e.g. class="button text" instead of class="button-text". This gives you:
.text {
text-align: center;
}
.button.text {
/*some properties*/
}
.header.text {
/*other properties*/
}
Unfortunately, this approach has to be ruled out if you need to support MSIE 6.0, all other browsers (including newer MSIE versions) deal with multiple classes correctly. As other people already noted which solution you choose is mainly a question of maintenance - choose the one that will be easier to change and adapt to new requirements.
Maintainability is king. Whatever you find most easy to maintain - in my opinion, this is your second example.
It depends how much you will center text, the issue with the second point is that you could then end up with a long list of classes added to each element in your HTML which isn't so clean.
If these happen in, for example, a p tag a lot, then you'd possibly be better off putting one class in the parent so the children can inherit it.
i tend to group items together example like
.button-text, .header-text{
text-align:center
}
then if they need something unique add that to another
ie
.button-text{
font-size:22px;
}
.header-text{
font-size:44px;
}
class name's should be usefull but its not a biggie, just ensure they are unique. Often i name things based on their hierarchy within a page or section, as to prevent any accidental duplication.
I've got CSS on my links depending what type of link it is. In this case it's password protected, and external link.
So I've got CSS like this:
a.external-link:after { padding-left: 2px; content: url(../images/icon-external-link.gif); }
a.restricted-link:after { padding-left: 2px; content: url(../images/icon-lock.png);}
However when I try something like this:
<a class="external-link restricted-link" href="some link">Some Link</a>
It only displays the last icon, in this case the icon-lock.png. Which makes sense, since the content value can only be set once not combined, so the last class declaration is overwriting it. Is there anyway to combine these two so I can mix and match these link classes easily (I've got 4 total). I don't want to make separate classes/images for each combo.
Hate to break it to you, but you're going to have to make separate classes/images for each combo. Especially as there would be no way of knowing which content should go first.
a.external-link.restricted-link:after
{
content: url(ext) url(res);
}
vs
a.external-link.restricted-link:after
{
content: url(res) url(ext);
}
Is it possible to add additional rules to a css block when using a "{ (properties of x) }" selector?
I looked at references but I can't find anything related to "properties of x". A link would be wonderful. I tried the following two combinations, but neither worked:
.dock li { (properties of grid_2; display:inline; background-color:#666; ) }
.dock li { display:inline; background-color:#666; (properties of grid_2) }
Many thanks!
EDIT
Apparently I misread an article and thought that such a syntax existed. I thought one could create a class and let it inherit the properties of another using such syntax, which is evidently not the case.
CSS does not have such a feature.
What you are describing is not possible. I think there are two other possibilities you could maybe use. The first is, that you need to know that several styles can be applied to an element at the same time. I'll give you an example:
li { font-size: 10pt; }
.dock li { color: #ff0000; }
All list items will be formatted with a font size of 10 points and only those within an element containing the dock class will be red.
My second suggestion is that you try applying two or more classes to your HTML element, for instance:
.grid li { font-size: 10pt; }
.dock li { color: #ff0000; }
Now put the grid and dock class into your HTML, and the elements will apply both style definitions:
<ul class="grid dock"> ...
Whatever you consider best for your project: remember that the properties defined in the second style overwrite the properties of the first one (if they do not define the same properties at all, there will be no confusion).
maybe your question is not too strange..
What I understand is that you want to do something like:
.a { prop1: val; prop2: val; }
.b { prop3: val; prop4: val; }
.c { .a; .b; prop5: val; prop6: val; }
You want the class .c to inherit all the properties and values of .a and .b
If this is ok, you can do that using LESS.
To use your LESS code in your sites you have different ways to do it.
First of all check the original site: LESS.org
If you are on Mac check this site: LESS APP + PLUGINS
If you are on PC the less.js plugin should be easier to implement LESS in your sites: less.js usage
Hope it helps.
Happy coding y'all! :)
