I have two new 10–week web design courses, starting in January 2011.

For the Tuesday evening course at Blachington Mill School in Hove see Web Design with City College Brighton and Hove.

For the Thursday morning course at The Bridge in Brighton see Web Design at The Bridge.

In the 19th century many town houses were built with a coal cellar under the pavement in front of the house. Coal hole covers are the cast iron plates that cover the entrances to these cellars. Although no longer in use, many still exist and there are some beautiful designs. Here are some examples I have found around Brighton.

Recently I have been taking photographs of street furniture around Brighton, particularly Victorian boot scapers and coal hole covers. When you start looking for them you find them all over the place.

As a teenager in the 70’s I went swimming three or four times a week in Stevenage Swimming Pool. In those days health and safety was not taken too seriously, so we had a 6ft springboard, running jumps from a 12ft top board and could play all kinds of games such at jostling to retrieve a pair of goggles placed at the bottom of the 12ft deep-end. Sometimes, late in the day when the mums and dads had left, we had mass games of ‘he’ in which even the lifeguards joined in. Racing up to the top board to run and jump out as far as you could with someone in hot pursuit was a fun tactic in that game.

I guess it taught me to be confident in the water, but these days I never swim in an indoor pool. After leaving Stevenage I rejected chlorinated captivity and started to swim in the wild, in lakes, rivers and the sea.

I’m a bit of a wimp when it comes to cold water, so most of my memorable swims have been in the tropics. Now, reading Roger Deakin has inspired me to do more wild swimming in England. This photograph is from a swim in the Cuckmere in Sussex a few days ago.

This is a photograph of the macropterous (long-winged) form of Roesel’s bush-cricket, Metrioptera roeseli, taken near Ebernoe Common in West Sussex a few days ago. This form usually appears in hot summers, enabling the species to extend its geographical range quickly. The species arrived in England in the 1990’s, probably as a result of the warming climate.

There are many techniques for putting rounded corners on a box. All of them require some deviation from the ideal of clean, semantic (X)HTML for structure, CSS for presentation and scripting for behaviour.

The technique of placing corner images directly in a page goes against the idea that CSS should be used for presentation and reduces flexibility (no style-switching). Techniques that use JavaScript seem like overkill to me, and the resulting page code is often the same anyway.

Best let CSS handle it. The cleanest and most concise way I have found uses four <div> elements to call the corner images from a stylesheet.

The code for the page.

The code for the stylesheet.

Pretty straightforward. Using empty <div> elements for presentation like this looks a bit messy but I do not think it is incorrect. The comments are added because some browsers will add default dimensions to an empty <div>. The <div> elements are nested so that there is no need to declare a width on the classes.
