Show url content html

The url() CSS function is used to include a file. The parameter is an absolute URL, a relative URL, a blob URL, or a data URL. The url() function can be passed as a parameter of another CSS functions, like the attr() function. Depending on the property for which it is a value, the resource sought can be an image, font, or a stylesheet. The url() functional notation is the value for the data type.

Note: There is a difference between a URI and a URL. A URI identifies a resource. A URL is a type of URI, and describes the location of a resource. A URI can be either a URL or a name (URN) of a resource.

In CSS Level 1, the url() functional notation described only true URLs. In CSS Level 2, the definition of url() was extended to describe any URI, whether a URL or a URN. Confusingly, this meant that url() could be used to create a CSS data type. This change was not only awkward but, debatably, unnecessary, since URNs are almost never used in actual CSS. To alleviate the confusion, CSS Level 3 returned to the narrower, initial definition. Now, url() denotes only true s.

/* Simple usage */ url(https://example.com/images/myImg.jpg); url(data:image/png;base64,iRxVB0…); url(myFont.woff); url(#IDofSVGpath); /* associated properties */ background-image: url("star.gif"); list-style-image: url('../images/bullet.jpg'); content: url("pdficon.jpg"); cursor: url(mycursor.cur); border-image-source: url(/media/diamonds.png); src: url('fantasticfont.woff'); offset-path: url(#path); mask-image: url("masks.svg#mask1"); /* Properties with fallbacks */ cursor: url(pointer.cur), pointer; /* Associated short-hand properties */ background: url('star.gif') bottom right repeat-x blue; border-image: url("/media/diamonds.png") 30 fill / 30px / 30px space; /* As a parameter in another CSS function */ background-image: cross-fade(20% url(first.png), url(second.png)); mask-image: image(url(mask.png), skyblue, linear-gradient(rgba(0, 0, 0, 1.0), transparent)); /* as part of a non-shorthand multiple value */ content: url(star.svg) url(star.svg) url(star.svg) url(star.svg) url(star.svg); /* at-rules */ @document url("https://www.example.com/")  /* … */ > Experimental @import url("https://www.example.com/style.css"); @namespace url(http://www.w3.org/1999/xhtml);

Relative URLs, if used, are relative to the URL of the stylesheet (not to the URL of the web page).

Syntax

Values

A string which may specify a URL or the ID of an SVG shape.

A URL, which is a relative or absolute address, or pointer, to the web resource to be included, or a data URL, optionally in single or double quotes. Quotes are required if the URL includes parentheses, whitespace, or quotes, unless these characters are escaped, or if the address includes control characters above 0x7e. Double quotes cannot occur inside double quotes and single quotes cannot occur inside single quotes unless escaped. The following are all valid and equivalent:

: url("https://example.com/image.png") : url('https://example.com/image.png') : url(https://example.com/image.png)

If you choose to write the URL without quotes, use a backslash ( \ ) before any parentheses, whitespace characters, single quotes ( ‘ ) and double quotes ( » ) that are part of the URL.

References the ID of an SVG shape — circle , ellipse , line , path , polygon , polyline , or rect — using the shape’s geometry as the path.

In the future, the url() function may support specifying a modifier, an identifier or a functional notation, which alters the meaning of the URL string. This is not supported and not fully defined in the specification.

HTML Links

Links are found in nearly all web pages. Links allow users to click their way from page to page.

HTML Links — Hyperlinks

HTML links are hyperlinks.

You can click on a link and jump to another document.

When you move the mouse over a link, the mouse arrow will turn into a little hand.

Note: A link does not have to be text. A link can be an image or any other HTML element!

HTML Links — Syntax

The link text is the part that will be visible to the reader.

Clicking on the link text, will send the reader to the specified URL address.

Example

This example shows how to create a link to W3Schools.com:

By default, links will appear as follows in all browsers:

An unvisited link is underlined and blue
A visited link is underlined and purple
An active link is underlined and red

Tip: Links can of course be styled with CSS, to get another look!

HTML Links — The target Attribute

By default, the linked page will be displayed in the current browser window. To change this, you must specify another target for the link.

The target attribute specifies where to open the linked document.

The target attribute can have one of the following values:

_self — Default. Opens the document in the same window/tab as it was clicked
_blank — Opens the document in a new window or tab
_parent — Opens the document in the parent frame
_top — Opens the document in the full body of the window

Example

Use target=»_blank» to open the linked document in a new browser window or tab:

Absolute URLs vs. Relative URLs

Both examples above are using an absolute URL (a full web address) in the href attribute.

A local link (a link to a page within the same website) is specified with a relative URL (without the «https://www» part):

Example

Absolute URLs

W3C

Google

Relative URLs

HTML Images

CSS Tutorial

HTML Links — Use an Image as a Link

To use an image as a link, just put the tag inside the tag:

Example

Link to an Email Address

Use mailto: inside the href attribute to create a link that opens the user’s email program (to let them send a new email):

Example

Button as a Link

To use an HTML button as a link, you have to add some JavaScript code.

JavaScript allows you to specify what happens at certain events, such as a click of a button:

Example

Tip: Learn more about JavaScript in our JavaScript Tutorial.

Link Titles

The title attribute specifies extra information about an element. The information is most often shown as a tooltip text when the mouse moves over the element.

How to Display Dynamic Content on a Page Using URL Parameters

In this tutorial, I will show you how to show/hide dynamic content based on URL parameters for any web page. This solution uses HTML, CSS and JavaScript instead of backend coding, so you will be able to use it with Marketo, Pardot, or any other system that allows a bit of custom code.

The HTML

Wrap each one of your dynamic content sections in a DIV and add a class called dynamic-content. Also, give each DIV a unique ID. We will reference these later in the JavaScript.

  This is the default content
  I like apples
  I like oranges
  I like bananas

The CSS

There’s only one line of CSS needed to hide all the elements on the page since JavaScript will be used to show/hide the content.

The JavaScript

This is the complicated part. First, we need to parse the URL and check for a specific parameter. For this example I will be using the parameter name “dc”, so in this case, my URL would look like this:

https://jennamolby.com/my-webpage?dc=mycontent

This is the piece of code to parse the URL. You can change “dc” to be whatever parameter name you want.

// Parse the URL parameter function getParameterByName(name, url) < if (!url) url = window.location.href; name = name.replace(/[\[\]]/g, "\\$&"); var regex = new RegExp("[?&]" + name + "(=([^&#]*)|&|#|$)"), results = regex.exec(url); if (!results) return null; if (!results[2]) return ''; return decodeURIComponent(results[2].replace(/\+/g, " ")); >// Give the parameter a variable name var dynamicContent = getParameterByName('dc');

Use jQuery to show/hide dynamic content

To make things easier, we’ll use jQuery to show/hide the content, in conjuction with the javascript. You can add in as many conditions as you want, just make sure you always include default content just in case parameters are misspelled or not in the URL.

The full JavaScript code

Here’s the full piece of javascript and jQuery code.
