The <a> tag defines a hyperlink. The
href attribute specifies the URL of the page
the link goes to:
<a href="www.peskypixie.co.uk">A link to the pesky pixie website</a>
The <img> tag is used to embed an
image in an HTML page. The src attribute
specifies the path to the image to be displayed:
<img src="Peskybookbanner_sml.jpg">
There are two ways to specify the URL in the src
attribute:
1. Absolute URL - Links to an external image that is hosted on another website. Example: src="https://www.w3schools.com/images/img_girl.jpg".
Notes: External images might be under copyright. If you do not get permission to use it, you may be in violation of copyright laws. In addition, you cannot control external images; it can suddenly be removed or changed.
2. Relative URL - Links to an image that is hosted within the website. Here, the URL does not include the domain name. If the URL begins without a slash, it will be relative to the current page. Example: src="img_girl.jpg". If the URL begins with a slash, it will be relative to the domain. Example: src="/images/img_girl.jpg".
Tip: It is almost always best to use relative URLs. They will not break if you change domain.
The <img> tag should also contain the
width and
height attributes, which specifies the width and
height of the image (in pixels):
<img src="images1/Peskybookbanner_sml.jpg" width="350px" height="350px">
The required alt attribute for the <img>
tag specifies an
alternate text for an image, if the image for some reason cannot be displayed.
This can be due to
slow connection, or an error in the src attribute, or if the user uses a screen
reader. See what happens if the source attribute is empty:
<img width="20%" height="20%" src="" alt="peskypixiebook">
The title attribute defines some extra
information about an
element.
The value of the title attribute will be displayed as a tooltip when you mouse over the element:
<p title="I'm a tooltip">This is a paragraph.</p>
This is a paragraph.
The style attribute is used to add styles to
an element, such as color, font, size, and more.
<p style="color:red;">This is a red paragraph.</p>
This is a red paragraph.
You should always include the lang attribute
inside the <html> tag, to declare the
language of the Web page. This is meant to assist search engines and browsers.
The following example specifies English as the language:
<!DOCTYPE html>
<html lang="en">
<body>
...
</body>
</html>
The HTML standard does not require lowercase attribute names.
The title attribute (and all other attributes) can be written with uppercase or lowercase like title or TITLE.
However, W3C recommends lowercase attributes in HTML, and demands lowercase attributes for stricter document types like XHTML.
The HTML standard does not require quotes around attribute values.
However, W3C recommends quotes in HTML, and demands quotes for stricter document types like XHTML.
Double quotes around attribute values are the most common in HTML, but single quotes can also be used.
In some situations, when the attribute value itself contains double quotes, it is necessary to use single quotes:
<p title='Pesky "As Always" Pixie'> Pesky ToolTip </p>
Pesky ToolTip
<p title="Pesky 'As Always' Pixie"> Pesky ToolTip </p>
Pesky ToolTip
