The <img> tag is empty, which means that it contains attributes only, and has no closing tag.
...

Cancel
To display an image on a page, you need to use the src attribute. Src stands for "source". The value of the src attribute is the URL of the image you want to display.

<img src="url" alt="some_text">

  The required alt attribute specifies an alternate text for an image, if the image cannot be displayed.
  
  <div class="cArrow"> </div><div class="cContentInner">The required alt attribute specifies an alternate text for an image, if the image cannot be displayed.</div>

The browser displays the image where the <img> tag occurs in the document. If you put an image tag between two paragraphs, the browser shows the first paragraph, then the image, and then the second paragraph.
...

Cancel
The height and width attributes are used to specify the height and width of an image.
...

Cancel
The attribute values are specified in pixels
...

Cancel
alt="
...

Cancel
height="
...

Cancel
<img src="
...

Cancel
width="
...

Cancel
It is a good practice to specify both the height and width attributes for an image. If these attributes are set, the space required for the image is reserved when the page is loaded.
...

Cancel
without these attributes, the browser does not know the size of the image. The effect will be that the page layout will change during loading
...

Cancel
Loading images takes time

An external style sheet is ideal when the style is applied to many pages

Each page must link to the style sheet using the <link> tag. The <link> tag goes inside the <head> section
