I am trying to style all the headings in my header with a different font-family than the headings on the rest of the page but I am having trouble getting the style to only apply to the specific header ID.
Here is what I tried:
#header h1,h2,h3,h4 {
font-family:'Helvetica';
}
But this causes all h1/2/3/4 tags to use the Helvetica font regardless of if they are in the header div or not. I'm sure I am missing something simple, can anyone help? Thanks!
I think you must do so:
#header h1,#header h2, #header h3, #header h4 {
font-family:'Helvetica';
}
You need to target all hN with the ID.
#header h1,
#header h2,
#header h3,
#header h4 {
font-family:'Helvetica';
}
See Fiddle
I have checked and checked and I'm sure it's something simple I've overlooked but my font is not displaying.
The first paragraph is suppose to have quotes around it (you will see it has them right now because I did it without font-awesome); however, you will see the second full paragraph is suppose to have a quote at the beginning and it's not displaying. Please help

Your CSS specificity is being overridden by a style in style.css.
Font-Awesome only has:
.fa { font-family: FontAwesome }
Yet your style overrides the font-family (note the !important):
#fake, .menu, a.signin span, .balloon_text, #footer, #footer a, #signin_menu p a, #learning_center h2, #hst_blog h2, #carriers h2, #career_center h2, #learning_center, #hst_blog, #carrier_careers, .entry-title, #sidebar, #sidebar a, .breadcrumbs a, .breadcrumbs, #searchform input, .page-title, .entry-content, .entry-content a, .entry-utility, .read_more, #content h1, #content h2, #content h3, #content h4, #content h5, #content h6, .widget-title, #live_chat a, #hst_careers, #apply_online, #sales_revenue, #hst_compensation, #search_agents, #search_map, .agent_search, #search-results, #usca-intro-text, .usca-plan, #usca-form {
font-family: 'AllerRegular',Arial,Helvetica,sans-serif !important;
font-weight: normal;
}

Check, if you use selector *
*{font-family: Arial}
in your default stylesheet.
Is there a more efficient way to select multiple parent and descendant groups?
What I have now:
aside p, aside h1, aside h2, aside h3, aside h4,
article p, article h1, article h2, article h3, article h4,
section p, section h1, section h2, section h3, section h4 {
width: 75%;
padding: 15px 0;
margin: 0 auto;
text-align: center;
}
:matches()
You can use the :matches() CSS pseudo-class function to group your parents and descendants:
:matches(aside, article, section) :matches(p, h1, h2, h3, h4)
Note that, at the time of writing, this is still an experimental technology, so you may want to view the browser compatibility before using this in production.
Older browsers may require using the vendor-prefixed pseudo-class :any():
:-moz-any(aside, article, section) :-moz-any(p, h1, h2, h3, h4),
:-webkit-any(aside, article, section) :-webkit-any(p, h1, h2, h3, h4),
:matches(aside, article, section) :matches(p, h1, h2, h3, h4)
According to CSSWG issue #3258, :matches() might be renamed to :is() in the future:
:is(aside, article, section) :is(p, h1, h2, h3, h4)
You could remove all the tag specificity.
p, h1, h2, h3, h4 {
width: 75%;
padding: 15px 0;
margin: 0 auto;
text-align: center;
}
Using pure CSS, your current way is probably the most efficient means, other than setting a class on all the h tags.
Using LESS, you could do something like this:
aside, article, section {
h1, h2, h3, h4 { ... }
}
if there are only (p, h1-h4) in parents you can do that:
aside > *, article > *, section > * {
width: 75%;
padding: 15px 0;
margin: 0 auto;
text-align: center;
}
it will affect only direct children.
The most performant, concise and specific selector would simply be:
.selector {
width: 75%;
padding: 15px 0;
margin: 0 auto;
text-align: center;
}
it could be opinable that it will pollute your markup but in pure terms of css performance this is it.
with regards to * selector, its performance is poor and adding a parent selector will NOT improve the situation, as illustrated here
The style system matches rules by starting with the key selector, then moving to the left (looking for any ancestors in the rule’s selector). As long as the selector’s subtree continues to check out, the style system continues moving to the left until it either matches the rule, or abandons because of a mismatch.
one last remark, aside, article, section are not supported in IE < 8 so any styling won't be picked up by those browsers (unless a polyfill is used but that is a JS only way)
I'd like to target all h tags on a page. I know you can do it this way...
h1,
h2,
h3,
h4,
h5,
h6 {
font: 32px/42px trajan-pro-1,trajan-pro-2;
}
but is there a more efficient way of doing this using advanced CSS selectors? e.g something like:
[att^=h] {
font: 32px/42px trajan-pro-1,trajan-pro-2;
}
(but obviously this doesn't work)
No, a comma-separated list is what you want in this case.
If you're using SASS you could also use this mixin:
#mixin headings {
h1, h2, h3,
h4, h5, h6 {
#content;
}
}
Use it like so:
#include headings {
font: 32px/42px trajan-pro-1, trajan-pro-2;
}
Edit: My personal favourite way of doing this by optionally extending a placeholder selector on each of the heading elements.
h1, h2, h3,
h4, h5, h6 {
#extend %headings !optional;
}
Then I can target all headings like I would target any single class, for example:
.element > %headings {
color: red;
}
It's not basic css, but if you're using LESS (http://lesscss.org), you can do this using recursion:
.hClass (#index) when (#index > 0) {
h#{index} {
font: 32px/42px trajan-pro-1,trajan-pro-2;
}
.hClass(#index - 1);
}
.hClass(6);
Sass (http://sass-lang.com) will allow you to manage this, but won't allow recursion; they have #for syntax for these instances:
#for $index from 1 through 6 {
h#{$index}{
font: 32px/42px trajan-pro-1,trajan-pro-2;
}
}
If you're not using a dynamic language that compiles to CSS like LESS or Sass, you should definitely check out one of these options. They can really simplify and make more dynamic your CSS development.
The new :is() CSS pseudo-class can do it in one selector.
For example, here's how you could target all headings inside a container element:
.container :is(h1, h2, h3, h4, h5, h6)
{
color: red;
}
Most browsers now support :is(), but keep in mind that most browsers made before 2020 didn't support it without a prefix, so be careful about using this if you need to support older browsers.
In some cases, you may instead want to use the :where() pseudo-class, which is very similar to :is() but has different specificity rules.
SCSS+Compass makes this a snap, since we're talking about pre-processors.
#{headings(1,5)} {
//definitions
}
You can learn about all the Compass helper selectors here:
Here is my attempt to solve this problem with (modern) CSS only.
Context : Inside of Joplin (very nice note taking app, link), there is an userfile.css in which you can write your custom CSS for display and export of markdown notes.
I wanted to target all headings directly after (adjacent sibling) certain tags, namely p, ul, ol and nav to add a margin in between. Thus :
p + h1,
p + h2,
p + h3,
p + h4,
p + h5,
p + h6,
ul + h1,
ul + h2,
ul + h3,
ul + h4,
ul + h5,
ul + h6,
ol + h1,
ol + h2,
ol + h3,
ol + h4,
ol + h5,
ol + h6,
nav + h1,
nav + h2,
nav + h3,
nav + h4,
nav + h5,
nav + h6 {
margin-top: 2em;
}
WOW. Very long. Such selectors.
I then came here, learnt, and tried :
p + :is(h1, h2, h3, h4, h5, h6),
ul + :is(h1, h2, h3, h4, h5, h6),
ol + :is(h1, h2, h3, h4, h5, h6),
nav + :is(h1, h2, h3, h4, h5, h6) {
margin-top: 2em;
}
Hmm. Much shorter. Nice.
And then, it struck me :
:is(p, ul, ol, nav) + :is(h1, h2, h3, h4, h5, h6) {
margin-top: 2em;
}
Yay, this also works! How amazoomble!
This might also work with :where() or other CSS combinators like ~ or even (space) to create "matrix" of CSS selectors instead of very long lists.
Credits : all the answers on this page referencing the :is() selector.

for n in 1..6
h{n}
font: 32px/42px trajan-pro-1,trajan-pro-2;
The jQuery selector for all h tags (h1, h2 etc) is " :header ". For example, if you wanted to make all h tags red in color with jQuery, use:
$(':header').css("color","red")
July 2022 update
The future came and the :is selector is what you're looking for as described in this answer given in 2020 by #silverwind (now the selected answer).
Original answer
To tackle this with vanilla CSS look for patterns in the ancestors of the h1..h6 elements:
<section class="row">
<header>
<h1>AMD RX Series</h1>
<small>These come in different brands and types</small>
</header>
</header>
<div class="row">
<h3>Sapphire RX460 OC 2/4GB</h3>
<small>Available in 2GB and 4GB models</small>
</div>
If you can spot patterns you may be able to write a selector which targets what you want. Given the above example all h1..h6 elements may be targeted by combining the :first-child and :not pseudo-classes from CSS3, available in all modern browsers, like so:
.row :first-child:not(header) { /* ... */ }
In the future advanced pseudo-class selectors like :has(), and subsequent-sibling combinators (~), will provide even more control as Web standards continue to evolve over time.
Plain CSS
With plain css you have two ways. This targets all the heading elements wherever they are inside the page (as asked).
:is(h1, h2, h3, h4, h5, h6) {}
This one does the same but keeps the specificity to 0.
:where(h1, h2, h3, h4, h5, h6) {}
With PostCSS
You can also use PostCSS and the custom selectors plugin
#custom-selector :--headings h1, h2, h3, h4, h5, h6;
:--headings {
margin-top: 0;
}
Output:
h1,
h2,
h3,
h4,
h5,
h6 {
margin-top: 0;
}
You could .class all the headings in Your document if You would like to target them with a single selector, as follows,
<h1 class="heading">...heading text...</h1>
<h2 class="heading">...heading text...</h2>
and in the css
.heading{
color: #Dad;
background-color: #DadDad;
}
I am not saying this is always best practice, but it can be useful, and for targeting syntax, easier in many ways,
so if You give all h1 through h6 the same .heading class in the html, then You can modify them for any html docs that utilize that css sheet.
upside, more global control versus "section div article h1, etc{}",
downside, instead of calling all the selectors in on place in the css, You will have much more typing in the html, yet I find that having a class in the html to target all headings can be beneficial, just be careful of precedence in the css, because conflicts could arise from
Using scss you can loop through 6 and append to an empty variable $headings using a comma separator
$headings: ();
#for $index from 1 through 6 {
$headings: list.append($headings, h#{$index}, $separator: comma);
}
#{$headings} {
--default: var(--dark);
color: var(--default);
}

Let's say I have this table:
<table class="live_grid">
<tr>
<td>
<h3>Something!</h3>
</td>
</tr>
</table>
If I want to style the <h3> within the table, I can use this CSS selector:
.live_grid h3 {
}
This works fine. The trouble pops up if I want to style all headings in that table. I have tried this:
.live_grid h1,h2,h3,h4,h5,h6 {
}
This seems to match headings that are not within my table with the class of live_grid.
I'm sure this is a simple problem and right in front of me. Can you point out what I'm doing wrong?
Modern Option
Note: it may not be compatible with older browsers:
.live_grid :is(h1,h2,h3,h4,h5) {
/* style here */
}
See here for more information about :is(): https://developer.mozilla.org/en-US/docs/Web/CSS/:is
Standard Option:
If you want to style all the headers in that class, you have to do it like this (which could also be done without the line breaks). Notice each selector has .live_grid in it:
.live_grid h1,
.live_grid h2,
.live_grid h3,
.live_grid h4,
.live_grid h5,
.live_grid h6 {
/* style here */
}
When you comma separate things, they're independent of each other - hence the need to reference the class again.
For example:
#myDiv1, .live_grid, #myDiv2 {
color: blue;
}
This would set the text-color for everything in the #myDiv1 element, everything in the #myDiv2 element, and everything in the .live_grid element to having text color blue.
This also explains the reason your CSS is matching all the headers - you're referencing them individually, separated by commas - there is no selector for their containing element(s).
CSS pre-processor option
Or, you can always go with something like LESS or SASS which allows you to write nested rules something like this:
#live_grid {
h1, h2, h3, h4, h5, h6 {
/* style here */
}
}
Custom class option
Lastly, you could add a class to all of your headers and just refer to that class:
<-- HTML -->
<h1 class="custom-header">Title of Blog Post</h1>
<h2 class="custom-header">Subtitle of Blog Post about Pizza</h2>
/* CSS */
.custom-header {
/* style here */
}
.live_grid h1,
.live_grid h2,
...
you get the idea
Unfortunately, you'll need to target each heading separately, or just assign a class to it.
.live_grid h1,
.live_grid h2,
.live_grid h3,
.live_grid h4,
.live_grid h5,
.live_grid h6 {
}
I would just assign a class to the heading, or be specific about which headings you actually want to target.
Try this one:
.live_grid h1,
.live_grid h2,
.live_grid h3,
.live_grid h4,
.live_grid h5,
.live_grid h6 {}
The code
.live_grid h1,h2,h3,h4,h5,h6 {}
will only select the h1 that is with in .live_grid. Use
.live_grid h1,.live_grid h2,.live_grid h3,.live_grid h4,.live_grid h5,.live_grid h6 {}
From Adam Roberts' "Selector Grouping":
We can think of the comma as a logical OR operator, but it’s important to remember that each selector in a group is autonomous. A common beginner’s mistake is to write groups like this:
#foo td, th {
⋮ declarations
}
A beginner might think that the above declaration block will be applied to all td and th elements that are descendants of the element with an ID of "foo". However, the selector group above is actually equivalent to this:
#foo td {
⋮ declarations
}
th {
⋮ declarations
}
To achieve the true goal, write the selector group as follows:
#foo td, #foo th {
⋮ declarations
}
each heading tag has to be qualified:
.live_grid h1, .live_grid h2, .live_grid h3, .live_grid h4, .live_grid h5, .live_grid h6
That's one of the things that sucks about CSS. If you want CSS to suck less you can use http://sass-lang.com/ and it will look like:
.live_grid {
h1, h2, h3, h4, h5, h6 {
/* styles here */
}
}
.live_grid h1,
.live_grid h2,
.
.
.
.live_grid h6 { //now add your style here }
Another solution could be to add a special class for every h element you want to your html markup, and then, in your CSS, you can write somthing like this:
.live_grid .myHeader
{
/* your styling */
}
