An HTML link takes you to another page. An tag defines an anchor point. The "href" attribute indicates where a user will be directed when they click on the link. Between the and the closing tag is the anchor text that will be displayed to the user.

When you create a web page, you can reference another web page or website. For example, you can start a blog and want to link to an article that you feel is relevant.

Hyperlinks, or links, are used to link one web page to another and allow users to quickly navigate between multiple web pages. hyperlinks can be used to link to other pages on your site or pages on different sites.

In this guide, we’ll go over the basics of hyperlink in HTML. We are going to talk about how the link goals together, how to create bookmark anchors and links to email addresses and web elements.

HTML hyperlink

A hyperlink HTML points to another web resource. A hyperlink is defined between a tag and a closing tag. The text between these two tags takes the user to the linked web resource when the link is clicked.

Hyperlinks are created using label. Here is the syntax for link in an HTML file:

the text between our URL link tags we specify in our opening tag . We use the href attribute to choose the destination URL. This could be an absolute URL or an absolute link like https://python.engineering or a URL to part of our site

Here is an example of a link pointing to the web address of the Karma Career home page:

HTML link tag types

There are three types of links that can be viewed in a browser. These are:

Some websites replace these colors, which mean s they appear differently, but these are the main types of links that you can define in HTML HTML hyperlink

.: targets

You can change the way a link opens . For example, let’s say you want to open a link in a new tab in the user’s web browser. This will ensure that the user does not lose their place on the

web page they are currently viewing. This is where the targetHTML link attribute comes in. Using the target link, you can specify where the browser should open the resource you connected to

>

There are four types of targets you can use, which are:.

Here is an example of some of these links in action:

Hyperlink HTM L: bookmark anchors

Hyperlinks HTML can also refer to a specific part of a HTML document. This is useful if you have a long webpage and want to direct a user to a particular place in the text.

Before you start using anchors For bookmarks, you must first set an ID attribute on the element you want the user to go to. Here is an example of declaring an ID attribute on a title on a web page:

we assigned the HTML header tag has the id subtitle3, which we can use as a reference in an link.

Here is an example of link that references this header:

instead of specifying a url in our href tag, we specify the ID of the item we want to link to. Let’s bring hash before id (#) so that the browser knows that the linked document is on our web page.

HTML anchor tag

An HTML anchor tag refers to the label. This tag links a user to another web resource. The "href" attribute defines the resource a user will be directed to when they click on the link.

Examples of HTML anchor tags

regard Let ’s some examples of using the HTML tag.

Relative URLs

If you are linking to a resource on the same HTML document that you are developing, you can use a relative URL. Relative URLs are also called local links and do not use " https: //www.sitename .com < / a> " syntax. instead of this, the relative URLs pointing to a specific file path Web resource on the local server.

Let’s say we create a link on the website of career Karma which should point to our blog. Instead of using an absolute URL, we can use a local URL, because our site is the Karma Career site. Here is the code we would use to create this link:

When we clicked on the Karma career blog text, we were directed to the / blog resource on our site

email address

The anchor tag can also be used to link to an email address . When you click on a link to an email address , the user’s default email program will open. the . user will be asked if they want to send a message to the specified email address

to connect to an email address , you must start the link with the mailto protocol: Here is an example of a link to an email address in HTML:

When we click on our link, our email program opens and asks us to send an email to " [email protected] ¬ª The. anchor tag can link to an element on a web page. You can create this link by specifying the ID of the element to which the anchor should point. Suppose we want a link that takes our user to the header Topic test on a web page. We could create this link using the following code:

When clicking on our link our webpage scrolls to the item with id test_heading.

conclusion

hyperlinks can be used in HTML to associate a web page or other resource. You can use hyperlinks to connect to resources on your site or any other website. In this guide, we have explained how to use hyperlinks in an HTML document.

With all this information, you are ready to create hyperlinks HTML like a master!

How to get an absolute file path in Python

3 answers

izb By izb

Given a path such as "mydir/myfile.txt", how do I find the file"s absolute path relative to the current working directory in Python? E.g. on Windows, I might end up with:

"C:/example/cwd/mydir/myfile.txt"
877

Answer #1

>>> import os
>>> os.path.abspath("mydir/myfile.txt")
"C:/example/cwd/mydir/myfile.txt"

Also works if it is already an absolute path:

>>> import os
>>> os.path.abspath("C:/example/cwd/mydir/myfile.txt")
"C:/example/cwd/mydir/myfile.txt"

How to check if a path is absolute path or relative path in a cross-platform way with Python?

3 answers

UNIX absolute path starts with "/", whereas Windows starts with alphabet "C:" or "". Does python have a standard function to check if a path is absolute or relative?

175

Answer #1

os.path.isabs returns True if the path is absolute, False if not. The documentation says it works in windows (I can confirm it works in Linux personally).

os.path.isabs(my_path)

How to join absolute and relative urls?

3 answers

I have two urls:

url1 = "http://127.0.0.1/test1/test2/test3/test5.xml"
url2 = "../../test4/test6.xml"

How can I get an absolute url for url2?

139

Answer #1

You should use urlparse.urljoin :

>>> import urlparse
>>> urlparse.urljoin(url1, url2)
"http://127.0.0.1/test1/test4/test6.xml"

With Python 3 (where urlparse is renamed to urllib.parse) you could use it as follow:

>>> import urllib.parse
>>> urllib.parse.urljoin(url1, url2)
"http://127.0.0.1/test1/test4/test6.xml"
