3.5.1 Header Tags

Refer 3.1.2

3.5.2 Italics and Bolding

Refer 3.1.5

3.5.3 Flashing Text

This is a non-standard tag (it only works with Netscape browsers) and can be very irritating if
used on large areas of text, so use it sparingly.

<blink> ... </blink> Place around text to make it flash. (If you’re not using Netscape Navigator
you’re really seeing an image that looks like the blink tag effect.)
The code could look like this:

<p>Place around text to make it <blink>flash</blink>.</p>

3.5.4 Moving Text

Another non-standard tag that can be as irritating as the <blink> tag is <marquee>. This can be
used to create a moving text effect, similar to some “matrix” type LED and illuminated signs.

Notes There are quite a few options to control the appearance of text formatted with this
tag, the main ones are listed below. This tag works on Internet Explorer and later versions
of Netscape Navigator.

In early versions of Netscape Navigator you will see the text as a normal paragraph, it will not
scroll.

<marquee ... > This tag starts the Marquee, the following four attributes should be
put in this tag before the closing >.
behavior="..." This attribute can be "scroll", "slide" or "alternate". Scroll makes the
text scroll all the way across, off the edge and then starts again. Slide
makes the text scroll in like "scroll" but it stops when it reaches the far
edge. Alternate makes the text bounce back and forth between its'
edges.
bgcolor="#..." This will change the colour of the background using the usual colour
conventions.
loop="6" Specifies the number of times the effect will run, e.g. six times, or you
can specify "infinite" or "-1" to loop continuously.
width="300" Specifies the width of the marquee effect in pixels, or you can specify
it as a percentage of the space available, e.g. "40%".
Message Text After the opening <marquee ... > tag type the text that will scroll.
</marquee> This is the end tag.
