The octothorpe or hash sign precedes the name of the ID attribute:
HTML: <div id="sidebar">
CSS: #sidebar { color: red; }
You can apply as many tags as you want. The CSS tags apply style to the content
You can layer CSS element above HTML easily. It can be done as :<style> #id { ... } </style>
CSS can be applied to a web page in three ways: inline style, a STYLE element in the HEAD of a page, or an external style sheet (or any combination of the three).CSS rule use a selector to determine which elements to apply the styling to and property:value rules to determine which styles to apply.
<p style="color:#FFFFFF;"></p> A: this is correct although it is better to store your CSS rules in separate files, which makes editing and changing CSS easier and allows for manipulating of the DOM nodes (in this case the P tag): CSS style for all P tags: p { style: color: red; } CSS style for one specific P tag: p#my-id { color: red; } HTML for the latter: <p id="my-id">some text which is now red</p> <p>this paragraph has the common formatting and won't be red</p>
instead of putting your CSS in a separate file, you can append it to the HTML tag itself like so: <span style="color: #000000; font-weight: bold;"> this is highly unrecommended though, because if you do your styling that way, you have a lot of mixing between HTML and CSS and editing the style (e.g. replacing large portions of CSS code to apply a new design to a site) WILL be a pain.
externally <link href="yourstylesheet.css" type="text/css" rel="stylesheet" /> style tags <style> /* put your style properties here*/ </style> inline <span style=/* put your style properties here*/>This is the HTML element the style effects </span> perhaps someone else can add the 4th?
Cascading Style Sheet
CSS stands for cascading style sheet and it is used to apply styling to websites and webpage's i.e. colour and font of text, colour and style of buttons etc. XML is for transporting xml data over the internet. Combined you can use xml and css to style up data and represent it over the internet on webpage's in a consistent way across different browsers
Usually placed in the <head> area at the top of the webpage document, the CSS style sheet looks like this: <style type="text/css" /> tag/class/id { property: value; property:value; } </style> The "tag" is what describes/gives properties to HTML tags, such as: <b>This text would be boldface.</b> The "class" is what describes/gives properties to HTML tags if you include this into the tag, such as: <div class="main">This text would have any properties/values described in the class up in the CSS.</div> Also: in the CSS, the class is always behind a period. The "id" is similar to the "class," but id's give them a name, or identification. They can be used to move to a certain spot on a webpage, like this: <a href="#id1">Click to go to ID #1</a> <a name="id1">The link above would take you to this text.</a> Also: in the CSS and the "a href" url, the id is always behind a pound symbol (#). If this doesn't answer your questions, visit www.w3schools.com - it's a very helpful website.
An ID in CSS is identified by the octothorpe symbol (#). An ID in CSS references the ID attribute in HTML and they should have the same name. For example lets say I have the following code in my HTML: <small id="copyright">Copyright &#169;2015 &#8212; David Trower. All Rights Reserved.</small> Notice the id="copyright" on the <small> element? That is the ID. In CSS, if I want to stylize this element by referencing that ID I would use the following CSS code: #copyright { color: #9CBDDE; } Notice how what follows the octothorpe (#) symbol in the CSS code is the same as the value of the ID attribute in HTML (both are the word copyright). An ID is to be a unique identifier within a document. It should appear once, and only once, within a single document.
You can use the style with the individual elements. Or you can also use them externally in CSS file.
It sounds like you want: External Style = P.photobox { } <p class="photobox">Blah Blah Blah</p>
