Adding Images in HTML Images are defined with the <img> tag
Image tags do not have closing tags The src tag must be included; src stands for “source” and this references the URL of the picture The alt tag is optional but recommended; alt stands for alternative text & is used to provide short descriptive info for an image if the user can not view the image

Adding Images in HTML Cont.
Only 3 types of images are displayed by all browsers .jpg .gif .png The browser displays the image where you place the <img> tag. Example: If you put an image tag between two paragraphs, the browser shows the first paragraph, then the image, and then the second paragraph. **There are some very important differences between these file types but we will discuss those at a later date.**

Adding Images in HTML Cont.
For images embedded with text, images can “float” with the text. The align tag can be added to the img tag to make the image either align left or right Images can be resized using HTML tags but it is good practice to keep the picture proportional (this is done to avoid “stretching” of pictures) Height & Width can be added to the tag to resize the image

Adding Images - REVIEW Code View: Browser View:
<img src=“car.gif” alt=“green racecar” height=“95” width=“151” align=“right”> Browser View: NOTE: Alternative text is shown when the cursor is placed over the object

Hyperlinking Images & Text in HTML
Both text and images can be linked to other pages or images via the hyperlink tag Example: <a href=“ or text that will be hyperlinked </a> - a space must be between the a & href - the website that the image or text is leading to must be in quotes - be sure to include </a> or everything past this tag will be hyperlinked - web addresses should be written with

Styling HTML with CSS CSS was introduced together with HTML 4, to provide a better way to style HTML elements. CSS can be added to HTML in the following ways: Inline - using the style attribute in HTML elements Internal - using the <style> element in the <head> section External - using an external CSS file
8
Inline Styles An inline style can be used if a unique style is to be applied to one single occurrence of an element. To use inline styles, use the style attribute in the relevant tag. The style attribute can contain any CSS property. The example below shows how to change the text color and the left margin of a paragraph:

Inline Styles <p style="color:blue;margin-left:20px;">This is a paragraph.</p>

HTML <blockquote> Tag
The <blockquote> tag defines a long quotation. Browsers usually indent <blockquote> elements. <blockquote> < p>Here is a long quotation here is a long quotation</p> < /blockquote>

HTML <blockquote> Tag
Here comes a long quotation: <blockquote>This is a long quotation. This is a long quotation. This is a long quotation. This is a long quotation. This is a long quotation.</blockquote> Notice that a browser inserts white space before and after a blockquote element. It also inserts margins for the blockquote element.
